Chapter Text
"Yoyo."
"Ryu. We're supposed to be training, please don't." They were inside one of the gyms with Isagi on the treadmill and Shidou doing leg presses. There were a few gathered in the room, mostly just other boys training their bodies since they didn't want to watch old games the whole time.
Neither boy stopped their workout but Isagi could hear sounds of offense coming from Shidou's direction.
"Jeez Yoyo, you're so mean. I was just going to ask an innocent question." He said as paused to increase the weight on the press.
"Your questions are rarely innocent."
"Anyway. Do you think your parents would be willing to open their marriage?"
"HUH?!" The question throws Isagi off so much that he ends up tripping over his feet and falling. He hits the treadmill and while thankfully uninjured lays stunned on the ground for a few seconds. Shidou laughs and one of the other boys in the room, one with gray hair and eyes and a split tongue, helps him up. He remembers seeing the boy around the building and he had even had a few conversations with him. Himizu Aiki, he believed was the boy’s name.
Isagi took a few seconds to gather himself before looking at Shidou with a concerned expression. “Why, pray tell, do you want my parents to open their marriage?”
“Well! I’m so glad you asked!” Shidou exclaimed, jumping off the press. “At first, I was coming from the idea of the fact, and you can’t get mad at me for this ‘cause it’s true, that your mom and maybe even your dad are kinda hot.”
“Ryuusei!”
“Anyway anyway! And if they opened their marriage, I could slide in and become your stepdad ‘cause I know that’d piss you off.”
Before Isagi could speak again, Himizu spoke up. The snake-like boy stood rather casually listening to the boys' conversation hands tucked into the pockets of his shorts. "Wait wait wait. Shidou right? What do Blueberry's parents over here look like before you continue?"
Shidou looks unreasonably giddy as he pulls out his phone. Scrolling through his pictures the blonde stops on a picture taken last year during summer break. The picture has Yoichi and Ryuusei sitting on a beach towel with their parents standing behind them. The boys looked relatively the same, their parents were the attention grabbers.
Ryuusei's mom looked a lot like him, if not better. Dark skinned with the same pink eyes and blonde hair as her son. She was built with firm muscles across her body. Under further questioning, Himizu learned that she was a thrower for track and field in her younger days and that she regularly worked out when she had the time. She wore a two-piece though not in the traditional sense, with swim trunks rather than a bikini bottom.
Next to her was a man that could only be Yoichi's father. Dad bod in every way. He was dressed in casual beach attire similar to his son with only a loose button-up as an addition. Short dark hair cropped around the ears and thick rectangular glasses made the man look like a school teacher, especially with how smiley the man was. Next to him was Yoichi’s mother, who had been the original topic of conversation. Her brown hair was pulled into a low ponytail that rested on her shoulder. Looking at her face it’s easy to tell who Yoichi took after, large doe eyes and rounded features, the only things he took from his father were the hair and eye color. Iyo was wearing a one piece with a see through flowy bit around her hip.
Himizu wolf whistled as he took in the picture much to Isagi’s dismay. Shidou smiled at the shorter boy's misery before turning his attention to Himizu and continuing his previous train of thought. "But then I was like, I wouldn't stand a chance trying to get with either of Yoyo's parents. But I still want to be an ever present annoyance in his life so I'll be his stepbrother."
"Ryuusei what is wrong with you??"
"Let me cook. Your parents open their marriage. My mom joins them. Then I get to walk around and tell people you're my little brother. Wouldn't that be great?"
Isagi doesn't get a chance to speak as Himizu lets out a sound somewhere between a cackle and a hiss. The lighter haired boy apparently finds the situation to be the funniest thing of all time, something Isagi doesn't truly get and really doesn't want to get.
It doesn't take Shidou long to join in on the laughter. Though, he takes Isagi's refusal to laugh as a challenge and slowly stalks closer to the younger. Isagi knows that look, he knows it because he's been on the receiving end of what comes next many times. So while the boy had never been a sprinter, he darts out the room as fast as he can Shidou hot on his heels.
Shidou's laughing as he chases Isagi around, all the while Isagi is shrieking and laughing so hard there's tears. He's grown out of the crybaby phase but too extreme of an emotion was quick to set off the waterworks. Isagi spots an open door and doesn't hesitate to dart inside, slamming the door shut behind him as he does.
He's got his back pressed to the door as he locks it just as Shidou starts hitting it.
To the blind eye, Isagi looks like he's on the verge of a panic attack coming straight out of a horror movie. He's got tears streaming down his face, sobbing as he lets out this hiccuping noise paired with breathless whimpers. In short, he looks terrified in the eyes of Karasu, Otoya, and Yukimiya.
When the noise on the door dies down, it's then Isagi looks up at the three upperclassmen. He's still shaking as he waves a little before sliding down the door and resting on the floor. Yukimiya approaches him first, slowly and carefully like Isagi might run if he moves too fast.
"Are you alright?" He asks, placing a steadying hand on Isagi's shoulder. He doesn't speak but instead just gives a thumbs up as he's led away from the door. It's Otoya that opens the door and it's Otoya that is subsequently jumped and scared by Shidou.
As Shidou gets an earful from the boy's, he quickly notices how Isagi smiles evilly in the background. Shidou can't help but feel a little offended and proud. Isagi, using those crybaby tears that used to have him paralyzed to one spot as means to get Shidou in trouble? Dastardly plan executed perfectly.
