"Senku, you okay?" Tsukasa asked the scientist as well as his boyfriend who had been acting weird ever since Tsukasa had agreed to help Matsukaze train.
"Ah yeah, just peachy!" Senku snapped, not turning away from fiddling with his... thing he was working on.
"Hey, come on. What's with you?" Tsukasa insisted, grabbing the other's shoulders and making him turn around to finally face him.
"I said I'm fine, you meathead! Just go back to your training Ginro's bodyguard since you're so busy with him after all!" Senku glared at him, but it was the slight extra hardening of his eyes at mentioning Matsukaze that gave Tsukasa an idea of what was going on.
"Senku... Are you jealous?" he asked incredulously, shoulders shaking with surpressed laughter.
The scoff he received was all the answer he needed.
"Are you serious? Senku, why would you even be jealous of Matsukaze of all people?" Tsukasa asked.
"Well, for starters, you had no problem at all with him fondling your tits!"
"Hey, at least calls them pecs."
"That's what you're focusing on?!"
"Right, what's more important is, do you wanna fonddle them right now to make it even?"
"Tsukasa!"
"Sorry, sorry," Tsukasa apologized with a chuckle before smiling gently down at the other, "But you off all people should be able to figure out that little moment meant nothing. Back then he was drunk and not fully aware of what he was doing, and he right away passed out. Also, he apologised for it as soon as he woke up." he calmly reminded him.
"Senku," he took cupped the other's cheek, "I promise I only see Matsukaze as an ally and potential friend. The only person I could ever be interested in for anything more is you." he promised.
To his relief this finally seemed to bring Senku as ease, him visibly softening and leaning into his hand.
"Kukuku. Right, guess that does make sense. Sorry for acting like an asshole, babe." he apologised.
"And what about being a hypocrite?" Tsukasa then asked.
"Scuse me? What then hell am I being a hypocrite about?" Senku asked with a frown.
"Have you seen the way both Gen and Kohaku rarely leave your side?" the fighter gave him a pointed look, resulting in them staring at each other for about ten seconds before they both snorted and broke into barely surpressed chuckles.
"Okay, okay, I get it. No more getting jealous about you being close with others when I'm just as close with my own friends. Actually, I'll have a talk with them both about it. I'm honestly ten billion percent sure it's more muscle memory that anything from before I turned into a taken man, but I know they'll back off if I tell them."
"Thank you." Tsukasa nodded gratefully because as calm as h brought it, he had been frustrated at times seeing Senku so close to others who he was pretty sure used to have crushes on him.
"So... Make up kiss?" Senku then asked, making Tsukasa laugh and lean down to peck his lips.
He'd never get tired of Senku's bluntness.
Then he realised something.
"Say, you never answered my question earlier. Do you want a turn fondling my chest or not?"
"Tsukasa!"
