The seme was trash. He would make the uke pick him up every time he went out drinking. I forgot, but the seme may or may have not cheated on the uke. The uke got fed up with the seme and they broke up. The seme then realized how much he loved the uke. Both of them were at a bar and the seme saw the uke with another guy. Then he suddenly collapsed/fainted. The uke saw that and immediately went to the seme. They got back together and at the end, their roles kinda got reversed. Now the uke was the one calling the seme to pick him up after drinking with friends.
So one day, the uke fell down the stairs and got amnesia. The seme was there and lied to him saying that they were boyfriends. Don’t remember what happened in between but near the end, the uke played a prank and pretended to get amnesia again. There was this other guy who also liked the uke and he did what the seme did and told the uke that he was his boyfriend, but the seme was also there and was like ‘no, I’m your boyfriend’ or sth like that. That’s all I remember.
It might be this though I'm not sure, can't remember if this had an amnesia aspect to it or if i'm mixing it up with something else

The pink haired girl is so creepy af! What is she doing in a romance webtoon? She should go star in a horror one and leave our couple alone so they can sort out their misunderstandings and communicate!!
Totally agree Lol
