I'm guessing after the black one got kidnapped he got saved by the brown one. But the brown one got beaten up by the gangster so he got amnesia and forgot him. And since the gangster is getting released the black one locked him to protect him. Since the brown one kind of saved him so he is treating him with affection.? Honestly this seems the most reasonable sequence of events for this story to me.
He didn't forget the ML. He remember everything. But he didn't recognise the ML because they are all grown up. I feel like ml wants to lock him up, at the same time he likes the brown guy.
Spoiler . . . . . Mc is actually the cause of ml kidnapping. Dude was forced to work under gangster. ,c was ordered to befriend ML to lure him in. But it's all good cause mc helped ML, and gangsters were arrested.
