He suggests that Yuya "take him back" and that his body is already prepared

Yuya appears

He discovers the uke is a virgin

He says he's going to send a copy to Yuya

Yuya is his childhood friend and he doesn't like that they're dating so he wants to make things "more interesting"

He asks him if he's dating a first year named Fujisaki Yuya

The photographer tells him that the best spot to take the photo is behind the bookshelf

The text is hard to read, so: He wants to take photos for the school newspaper and intentionally caught him alone

The two friends are arguing over the fact that they evidently always steal each other's boyfriends/partners
