it’s a yaoi where there’s there’s 2 friends in college. And seme is really possessive and likes the uke. They room together I think, and seme pretends to ? (Or actually did idk) sleep with someone at their place. Idk this is a bad explanation but they both like each other, and the BL shows both of their POVs. I remember uke having lighter hair. I think uke feels a little upset that the seme brought someone over to their place to do it.
