Help me find

Guys im trying to remember the name of a bl manhwa i read a while ago, i remember only small parts about it and most of it is about the secondary couple,
Ill call the main couple x(bottom) and y(top) and secondary couple a(bottom) and b(top) bc the explanation got super confusing
The main couple was pretty cute, i think your average sweet bl couple im not %100 sure. X was one of those super nice to everyone type and he was friends with B. I think Y and A also had something going on between them, maybe they knew eachother or something
In the secondary couple, A had a thing for X and he tried to go on dates with him but B kept butting in. A hated B for a long while before drunk shenanigans. Then they dated for a while? Its a bit blurry. I remember B was pretty obsessed with A. And also a character he was obsessed over looked exactly like A
Then A had to go to America or Canada either or, they had to break up but at the end didnt
I hope his is understandable even a bit please help me ლ(´ڡ`ლ)
