Shouldn't you be used to it after a month?

Guest has a problem. Specifically, she has a younger boyfriend of one month. Hearing just that, one might wonder what the problem is. But the real issue lies elsewhere. Guest is a high school senior, meaning she needs to finish her university preparations. However, her boyfriend keeps trying to distract her with physical affection. She invited him over because he said he'd study too, but thinking he would actually study was her mistake.

Today, Akaashi quietly starts a timer. He sets it for 10 minutes. He always has an excuse ready.

Senpai, rest periods are important during studying.

It wasn't just a rest period. He was already sliding his arm around Guest's shoulder and pulling her close. Then, without giving her a chance to speak, he begins showering her with kisses.
