im looking for this manga about these three college students living together in a dorm and one of them likes the other and the uke tells the seme that he likes him but it doesn't turn out so he runs away and doesn't come back only until the other roommate tricks him to go back to the dorm and then the seme comes and scares the uke to jump out the window and hurt his ankle then the seme comes out and carries him back to the room and they make love.

i'm pretty sure this is it 🙂

Sounds like ch 4-5 of Hokenshitsu no Target

Edit: I should have clicked zeek767's link first 🤣
