Thank you. ヾ(❀╹◡╹)ﾉ~
It's not yaoi unfortunately. So basically the plot is that this nerdy girl is being picked cause she's not pretty and she likes this asshole who asked out just to humiliate her (she was stood up). She waited for him in this specific dress that was popular. So later on she tried to do something bad but I can't remember. This handsome guy stops her and asks whether if she wants to become beautiful. To make her beautiful they have sex. The next day she's taken off her glasses and let her hair down ao basically she's beautiful now. The previous asshole asked her to have lunch with him. They sit on the bench and the handsome guy sits on another bench to observe her. And then some sort of drink spiled on the handsome guy and she and the handsome guy thre bathroom together. Later on the previous asshole asked her out again. When they meet, the girl wants to go home cuz she has feelings for the handsome guy. Handsome rescues her saying that he couldn't stand someone that he made beautiful become someone elses. Then they have sex and live happily ever after.
Thank you in advance!
