Chapter 1: New neighbors

Chapter Text


Characters introduction:

 

Eren Jaeger, 33, newly married, a successful surgeon nicknamed "The Sniper" due to his precise and steady hands.

Mikasa Jaeger, 28, Eren's wife, an interior designer.

Reiner Braun, 35, married for two years, an obsessive journalist who tracks down new politicians or candidates.

Historia Braun, 24, Reiner's wife, recently graduated from university.

 


Historia sighed boredly, flipping through videos on her favorite app recently. It was almost midnight, and she was still alone in this big bed.

 

She believed she would live a happy life after marrying Reiner but it seems she was a bit naive. Her marriage to him was her own choice, and she made it with full conviction after 3 months of their official dating.

 

She understood his absence and accepted the nature of his work. He might spend hours in his office in front of his computer trying to finish his articles or conduct investigations into the new person whose news he would track down, but the matter had become a little more extreme than she thought.

 

She almost forgot the last time he touched or kissed her. She was upset with him, as soon as his orgasm lifted, he rose to his office at home to complete his work, as if she's one of his forced homework assignments. She no longer saw his desire and need for her.

 

During this period, Historia was spending her time studying for job interviews until she got a job for the next school season. She has a few months before she starts working.

 

A comments notification arrived on a post she had published on the online marital problems page, which she had certainly posted on an anonymous account.

 

She was very desperate when she wrote it, hoping to find someone who shared the same situation as her or who might help her with something she didn't know.

 

@Marie, the twins' mother : "Dear writer, it's normal for the flame of love to fade over time in marriage, even if it's been a long time. When he gets home from work. Prepare dinner and a drink. Liven things up and surprise him with a stunning appearance. If men are predatory by nature, be a bold prey to your husband, Don't worry too much; most of us have been through this situation before.”

 

Historia said to herself, “Be a bold prey for your husband.” She snorted sarcastically before saying : “This is interesting. She must have gotten the twins this way... Let’s see the next comment..”

 

@Lara : “I'm afraid to say your husband is going through a period of regret or reversing his decision. He may feel like he rushed into marrying you, and to be honest, if he hasn't asked you to have sex with him, there must be someone out there doing it, so he doesn't feel a need for you. No matter how ugly you are, a man won't resist the idea of sharing his bed with a woman, so wake up and see if you're really interested in your marriage."

 

Historia closed her phone and spread her arms on the bed, frowning. How did things get this bad? She lived the most beautiful love story with Reiner in America. She wasn't the type who preferred men her own age or younger. Men older than her excite her. They understand the nature of life and relationships, and most of them don't enter into a relationship until they're well convinced of their partner.

 

It was too late to take Marie's advice, but Historia decided it was a good idea. She opened her closet and chose a dark red lace nightgown with details that showed off her body through the slits. She was excited to see his reaction. She applied matching lipstick and styled her blonde hair, curling a few strands. Then headed to the kitchen to get a drink and some cups when she heard the door open.

 

Excitement was evident on her face as she leaned against the wall separating the kitchen and the dining table. Reiner passed by her and... went into the kitchen, filled a cup with cold water from the outside tap in the refrigerator, put it in the sink, and paused for a moment, looking at her from afar.

 

Historia bit her lower lip seeing Reiner's gaze fixed on her, his eyes roaming her body from top to bottom. But he said nothing, standing still, his eyes fixed as if trying to get a better look. Historia smiled at the thought that his gaze was a good sign.

 

He exhaled a long breath before speaking in a deep voice, "It's late, Historia. Go to sleep and don't wait for me." He then added, heading to his office, "I'm tired, and I still have a few pages to write."

 

Historia postponed her disappointment for later and followed him carrying the drink and cups. She placed the bottle firmly on his desk, a sound coming from it, followed by the clinking of cups. She decided to follow the twins' mother's plan to the end.

 

She walked behind his chair and hugged him from behind, placing her head on his shoulder and her hand gently caressing the side of his cheek. "I don't feel like sleeping, Reiner. Actually, I was waiting for you. I missed you, love."

 

He sighed helplessly, taking her hand and kissing it. "I know, I miss you too, sweetheart. But... I'm SO busy with work lately.. Uh.. the selection of the new Minister of Justice is coming up, and I have to keep an eye on it. Maybe I'll get a lead that will lead me to a scoop."

 

Historia placed her fingers on the corner of his lips, making him silent for a moment. "Shh… Don't exhaust yourself with explanations now, I want you to exhaust yourself while you are on top of me~" She leaned down and whispered to him as she opened the first button of his shirt. “I cannot resist the desire to feel you inside me.."

 

She was excited by his response to her when he started kissing her knuckles, so she straddled his thighs, placing her hands on his chest, moving them up and down, until she reached his neck. "I was hoping our night would be wild in bed, but the office is okay too haha~"

 

He quickly interrupted her, grabbing both of her hands and standing up. Historia thought he was going to pick her up, kiss her, and then apologize for being busy in a way that would please her, but instead he pulled her out of the office and kissed her shallowly.

 

“I-I'm sorry, Hisu, I can't get carried away with you and I can't drink because I'm going to wake up early tomorrow... Come on, darling, go to sleep and I'll come too right away when I'm done... Good night.” He closed the door slowly with a awkward smile.

 

Historia stood outside, trying to process what had just happened. Her husband had just rejected her and pulled her out of his office, smiling sarcastically as she headed to her room. She looked in the mirror to check herself. Her self-confidence was a little shaken before today, but after what happened a short while ago, she thinks it will takes a lot to restore it. She ran her fingertips over the skin of her face and negative questions began to creep into her mind…

 

"Maybe I lack feminine qualities? Maybe Reiner didn't like the dark red color of my nightgown, white would have been better? Or...Or maybe my hairstyle looks too random!!"

 

She moved closer, contemplating her features. Perhaps she was ugly or had she gained weight after marriage? "I was rejected… My husband refused to spend time with me after he abandoned me for a long time!"

 

Historia sighed, trying to control her feelings, then she began to wipe off her lipstick and change her clothes into comfortable pajamas. Finally, she buried her body under the bed sheets, closing her eyes, hoping that sleep would spare her from blaming herself and overthinking.

 


The morning sun came out, disturbing Historia with its rays seeping in through the window. She pushed the blanket away with difficulty and looked at the clock. It was late. She lived in an empty house, with nothing to do except cleaning tasks, in which she can vent her anger and waste some of her time. She prepared her juice, ignoring every thought running through her head about last night.

 

She sipped her juice while watching the series ‘Extraordinary Attorney Woo’ This series gives her the amount of energy she needs for each day. She was engrossed in her sweet world until she heard voices in the corridor outside the house.

 

Her curiosity led her to the kitchen to watch the cameras screen and get a closer look. She knew that the house next to her had been empty since she moved. Apartments in this building are expensive, as its location is convenient and lively.

 

"Oh.. I'll finally have new neighbors. I'm tired of being the only resident on this floor." Historia mumbled to herself, drinking from her cup and trying to separate the transport workers from the owners of the house. “Oh, she must be the owner of the house, she looks young, she must be rich, she was able to cover the costs of-”

 

A woman with long black hair who looked to be in her mid-twenties raises her hand to hit a man’s palm, and they smile at each other. Historia knew that spying was not a good habit, but she pressed the volume button so that she could hear what was going on between them.

 

“We did it, honey, it was very stressful. Let’s go inside,” the woman said softly. She entered first and he grabbed the upper end of the door, stretching his huge body before entering and closing the door behind them.

 

"A Couple…" she muttered with interest as she left the kitchen. She continued her series, and at every cute shot that took place between the two heroes, she would sigh and complain about her luck and situation to the table.

 

"What is this drought that I am experiencing because of you, Reiner…”

 

She then completed cleaning the last corner of the apartment after her series ended. She won't rest until she sees the sparkle of the floor and the marble in the kitchen. "Perfect perfect peereffect !!"

 

She was now in the kitchen. She prepares her favorite vegetable salad and swore not to prepare anything for that computer worm (Reiner). "Let him eat his computer buttons if he is hungry. Who does he think he is? Tch~"

 

She suddenly heard the sound of the doorbell and turned lightly to the camera screen in the kitchen. “They are the neighbors… Oh, my neighbors, it is a new word to me..”

 

She stopped halfway when she realized that she was still wearing her ugly pajama, so she quickly put her robe over it. It's not an appropriate appearance for the first meeting with new neighbors, but it is better for them than to wait a few minutes until she's ready. She tied the belt of her robe, quickly checking her hair and practicing a smile before finally opening the door.

 

Her neighbor was wearing comfortable home clothes, which made her feel at ease. She smiled politely and said, "Hi ! I'm Mikasa Jaeger, your new neighbor. I wanted to introduce myself and apologize if we caused any chaos during our move."

 

Historia smiled back and returned her greeting with respect, "Oh, welcome, Mikasa...I'm Historia.. Historia Braun, and please don't apologize. I didn't hear any noise, and I wasn't doing anything important...so come in!" She stood aside and let her in. When she entered, she closed the door behind her.

 

As soon as Mikasa entered, she looked around the apartment, inspecting it silently before returning her gaze to Historia, placing a rectangular cake box on the table. Then they both headed towards the kitchen and Historia began preparing two cups of coffee.

 

“Actually, I don't like formalities very much. I just wanted to leave an impression on my first meeting with you,” Mikasa said as she tucked a lock of her hair behind her ear.

 

Historia smiled at her, placing the cup in front of her, then replied: “Then we will come to an understanding on this point. I don’t even wear what is appropriate for meeting guests, so please feel comfortable with me…"

 

“So how long have you been living in this building?” Mikasa asked after taking a sip of her cup of coffee.

 

“About two years ago, did you come from another city?”

 

“No, I lived in the suburbs, but my husband moved to work in a hospital near this area, and it would be tiring with berlin’s heavy transportation to move from our old house to here.” Mikasa paused for a moment before adding: “Oh and speaking of my husband, he wanted to come with me to say hello... But he had to do something important at the hospital so he quickly went, but he'll say hello later."

 

Historia put down the cup of coffee after sipping a little, then said, "That's okay, his work must be very hard."

 

Mikasa sighed slightly, sipping her cup as well and taking a look at the place. “Your house is very comfortable, do you live alone?”

 

“No, I'm married, and I also moved here right after my marriage. He is also at work, so I'll have him introduce himself later.”

 

Time passed and both women exchanged conversations in which they learned a little about each other, their preoccupations, and their interests. Historia introduced Mikasa to some nearby malls, and before she left, they exchanged phone numbers to agree on a date to go out someday.

 

Later, Historia was drying her hair after her long bath, wearing comfortable home clothes, when she heard the doorbell. She left the dryer and headed to the screen before heading directly to open the door.

 

A large man was standing majestically filling the space at the door, carrying a small box in his hand and wearing an imposing gray suit while gathering his hair in a man's bun. He extended his hand and Historia quickly shook hands with him.

 

  When his eyes fixed on her face and their hands touched, her brain short-circuited, it felt like she was in a romantic film. His gaze was intense and intense, as if he was studying every detail in her. Historia had not seen a man like him before, he was handsome, well built, and had a charming body, and he appeared to have a mature personality. It took her a few seconds to realize that he was still shaking her tiny hand while his huge hand engulfed hers…

 

"Eren Jeager, your new neighbor and Mikasa's husband, I apologize for not coming earlier."

 

Historia looked at him spontaneously. “O-Oh No No ! That's okay… I'm Historia Braun, it's nice to meet you, Mr.Jeager !”

 

A faint dimples appeared on his cheeks as he smiled slightly, adding to the charm to his handsome face as he looked at the pretty woman infront of him and noticed how flustered she got after greeting him. He let go of shaking her hand and then offering her a small wrapped box.

 

“It’s a pleasure to meet you too Mrs.Braun… Here's a little gift, I hope you like it."

 

Historia took the wrapped box and smiled softly as she held it in her hands. "Ah, you shouldn't have."

 

He chuckled softly and shook his head." It's just something small really.” He gave her a friendly smile and it made her heart skip a beat, her throat suddenly feeling very dry. She wasn't sure if the heat she felt in her cheeks was from embarrassment or attraction.

 

"Thank you so much" she managed to say, her voice sounding a bit hoarse.

 

“You’re welcome” he said softly, his gaze lingering on her face for a few moments before he looked away. "So… I hope we can get along well and be good neighbors."

 

"Yeah… of course," she said a soft smile on her lips. Then Eren left and she closed the door behind him.
