The trip to Yakushima was quite the long one, even by boat. Despite how exhausting it was, along with everything else, everyone still wanted to have a good time.
And what better way to have a good time is there than to go to the beach? And that's exactly what the members of SEES, including you, were going to do. After all, it is a nice day, and it's in the middle of summer.
Everything seemed to be just fine, from your perspective. The girls were wearing their swimsuits, Junpei was being weird about it, Makoto was... Probably zoned out the whole time, considering how uncaring he usually is, and Akihiko—
As soon as your eyes had been laid on him, your inner composure crumbled.
Akihiko was wearing a speedo. To a beach. Where anybody vacationing here could stumble upon him. Anytime somebody brought it up, he just looked completely unaware, saying something like, "It's better for swimming," or, "It's what athletes wear," or something like that.
And that'd be perfectly fine, if you were able to take him seriously like that. But, no. You absolutely couldn't. Just staring too long at his exposed legs made you almost burst out laughing.
He still didn't notice this, which only made the whole situation more awkward when he innocently suggested you swim a few laps with him. When you struggled to respond, he tilted his head in confusion. Usually, you'd at least humor him, right? He'd end up asking, "You do know how to swim, right? I can teach you, if you don't. Although, that'd be better at a pool..."
It's a wonder how someone can be so... oblivious. But, that's Akihiko for you. You'll probably have to say something, before this gets worse.
