Yes it’s true. And here is spoiled if you need:
MC(Uke)and ML(Seme)knew each other during school. ML was 14 at the time and ML liked MC, which sends him on an internalized homophobia breakdown because MC couldn’t accept his attraction to ML. MC and his friends and film ML. Videos got sent to ML’s mother who then had a breakdown and was hospitalized.
What we see now is the revenge from ML to MC. It’s worse because MLmany MC many times and got MC in gang a few times in order to make MC remember his past actions and understand how ML had felt at the time.

At first when ml told him about what happened in the past, he didn’t want to believe it. MC forgot all of memories of the time he knew ml because he whacks his head during a scuffle, so being told that hea minor especially it was ml who just tormented him, he couldn’t bring himself to believe it. But after being tormented more by Woojin(a gangster who helped training ml to fight)and his gang, mc lost consciousness and had a vivid dream of his lost memories.
He remembered everything after that and realized he was the one who pushed ml’s button to come back and do the same to him if ml felt wronged.
“Do you feel wronged? If you feel wronged, do the same to me” mc to young ml
“Hyung, I really…want to kill you”
“I always tell you, don't just talk shit, do whatever you want. Of course, if you have the power to”
ML came to mc and did what he did to him but a few times worse than he did to ml in the past.

The ending if you’re curious:
The main story ending isn’t good or happy ending. It’s a normal ending with MC and ML ended up together but MC was deeply dependent on ML and he had anxiety and mentally not ok which ML got MC some help with therapy(so nice of him after making mc suffer…)
Almost everyone doesn’t like the ending because why would a victim get together with his abuser? That’s why the story is heavy on Stockholm Syndrome.

Bro I’m sorry but that is not how you write Stockholm syndrome…. Of course people are mad at the ending, and you cannot say the ending is neither good nor bad, there is nothing good about how things end for the two of the characters a good ending would have been them separated on they’re side getting therapy, this is objectively a bad ending for them to be together.
