uke does well on the test, seme feels like he messed up, then uke tells seme to "stop messing around" and that he (uke) "knows the seme doesn't actually like him" and the seme feels betrayed, gets pissed off, and tells the uke that he was disgusting for getting into a fake relationship if he didn't actually like him. Then uke panics bc hes in love with the seme and realizes his thought process was stupid, so he tells seme they should sleep together (as a last ditch effort to keep him there). seme is mad again and tells uke he wanted to sleep with him bc he liked him, not just because he's horny. But then, seme recants and agrees to sleep with the uke as "revenge/teach him a lesson." But, as they get ready for their first time at the seme's house that weekend, the seme goes through a lot of effort to prepare candles and flowers for their first time bc he still loves the uke. Then, during sex, uke confesses that he really likes the seme and is sorry for his actions, and the seme tells him he understands and takes him back (from what i remember)
