I read a yaoi manga at one point and it goes something like this. The ml was I love with this guy from his highschool he had black hair and I think the ml had brown, few years down the line the brown haired ml is still pining after the guy.
One scene was where they were in a place where you play pool, the black haired guy was there "playing" with a girl and the brown haired guy was there watching, but it wasn't the first time this happened, everyone was talking about how annoying he was and what not.
Then he left,upset, a few days later the black haired guy texted him to meet up and he was overjoyed, when he reached the guy was no where in sight. In his sadness he drank while still there and he met another black haired guy that looked exactly like the guy that he liked. I think he threw up on the guy.
When he woke up he was in the guys apartment somewhat naked and the guy was next to him, Chickies were in his body and what not. They argued for a bit even though the new black haired guy was chuckling all this time. Then he told the browned hair guy he was the previous black haired guys brother. Both of them were very rich, if I remember correctly. And the browned haired guy owned a company( it was grooming dogs) the brown haired guy also dropped out of highschool. One of the last detail I remember is that the brown haired guy figured out they were both playing with him, and he was very upset at that fact
This actually hurts, the manhwa is chopping up the storyline, like the reason for the poem is basically he was rushing an assignment and he choose a popular Korean song that's about a poor family, so if they do the part where they pay attention to the poem later it won't make sense
