It takes place in a school.

The seme asks his friend to sleep with him, and his friend secretly likes him so he agrees. but the sex is without love, and he starts feeling sad, then his sempai tells him (the uke) to pretend to go out w/ him. but it turns out his sempai likes the uke and the seme gets jealous.

Thanks.
