Work Text:
Mitsuya stood back from the dress form, pins hanging from his lips, and he frowned. This fabric was driving him up the wall but he was determined to get it to sit how he wanted it. He just had to work out how. As he looked at it from different angles and tweaked the drape of it on the curves of the mannequin, he was so focused on his work that he almost missed the knock at the door. Pulling the pins from his mouth he opened the door to find Taiju’s imposing form staring down at him with an eyebrow raised.
“I hear you're dating my sister.” Taiju’s voice was steady, displaying zero emotion and giving nothing away on how he felt about Mitsuya and Yuzuha seeing each other. He was dressed in a suit that Mitsuya himself had made and with his hair tied back, he looked like he was headed into a meeting where he wanted to succeed by intimidating his colleagues.
Mitsuya, on the other hand, was casually dressed and not expecting to deal with anything more difficult than a fabric that wouldn't drape the way he wanted it to. He took a breath and stood tall, looking Taiju in the eye as he replied “Yeah, what of it?”
Taiju hummed and looked down the corridor before turning back to Mitsuya.
“I guess that depends on how many bathrooms you've fucked her in.” Taiju’s eyebrow twitched. Just a little, but Mitsuya saw it and remembered what Taiju had said at Mana’s birthday: ‘If any of you bastards are disgusting enough to fuck my sister in a bathroom of all places, I'll fucking kill you!’
“Oh, ah” Mitsuya smiled as he remembered last Sunday morning and rubbed his hand up his face. He wasn't looking at Taiju at that moment, probably should have before he answered. “Only the two, so far.”
Mitsuya didn't have time to react before Taiju’s fist connected with his cheek. It wasn't a hard punch, Mitsuya knew damn well that Taiju could hit harder than that, but still it had him reeling a bit.
Taiju smoothed out the sleeve of his suit jacket, took a deep breath and straightened his tie. He hummed again as Mitsuya leaned on his door, rubbing his hand up and down his cheek, and glared at him.
“Feel better now? Got it out of your system?” Mitsuya asked. “Because you know Yuzuha will let me know if she doesn't like the way I treat her. She's more than capable of standing up for herself.”
“Yeah, I know. Doesn't mean I won't step in.” Taiju frowned. “Where was the other bathroom?”
“Here.” Mitsuya inclined his head toward the back room.
“Well that's better than a public one, I guess.” Taiju rubbed a hand down his face.
Mitsuya grinned at him a little “Why don't you like bathroom sex?” He asked.
Taiju frowned and shook his head. “I don't know, I just find it gross.” He looked back to Mitsuya. “I'd really rather not think of my sister getting fucked in a public bathroom. She's worth more than that.”
Mitsuya couldn't really blame him for feeling that way. There were definitely standards he'd expect a guy to hold to while dating Mana and Luna. He'd just never thought Taiju cared so much about Yuzuha. They stood at the threshold of Mitsuya's apartment, having a stare down, Taiju steadying his breathing while Mitsuya rubbed his cheek.
Mitsuya opened the door wide and turned to walk to his kitchen. “You want a beer?” He asked.
Taiju thought for a moment before answering him. “Yeah sure, why not.” He closed the door after himself as he walked inside.
