Mitsuki sees Akihiro look away from him, which implies he was looking at him in the first place, but that's normal, right? To look at someone when they've made a fool of themselves and poured soda all over their clothes? Nothing noteworthy about that, but maybe Mitsuki can do something about that.

So yeah, with a small sigh Mitsuki does give up on the shirt and start hauling it off, along with his undershirt because that's wet too. They're both guys, there's nothing here Akihiro hasn't seen before, and if he does think there's anything worth looking at, Mitsuki's going to show it off before his buzz dies and he loses his nerve. He's not normally shy by any stretch but even for him (sober him, anyway), this is a little much. Once the shirt's off, he balls it up and wipes at his stomach with the drier part. Much more practical than showy but for all he knows Akihiro's straight as a pin and he's just made things weird. Better not to push too hard, no matter how much he'd like to.

"That does sound similar, actually! More like our dorm. I guess it's not that common for idols to all live together like we do, but it was cheaper when we were first starting out and now it's just familiar." He leans down to the coffee table, retrieves what's left of his drink and knocks it back. "Hold that thought for a minute? I'm gonna grab something else to put on. Do you want me to take your jacket, too?"
