He did, it was funny when he went to confront Jaewoo and Hyunjin and after coming to know the truth he cried like a baby. (Even his subordinates we're shocked, although later he threatened to kill them if they did not forget.) Bro didn't even cry at Jaewoo's funeral. He continues to visit their shop and eat there frequently.
I took a sentence from the Korean novel and translated with an app, somewhat it says this: not sure what he meant by the second part.
"Therefore, continue to love Hyunjin. Pour out your affection to the extent that you cannot die even if you want to. ??Then, someday, I will be able to meet Jaewoo again?? It won't be easy to get there, but i never thought of giving up."
Before that, he mentioned that he wouldn't leave things as they were, emphasizing that he had ample time and was quite persistent.
He's still lowkey obsessed with him, he gives Jaewoo gifts and shii, but that's it. I suppose the leak i gave was a bit inaccurate, he does NOT give up pursuing bro, but he's not that obsessed over him that he's forcefully splitting them up or kidnapping nd shiii.

Yeah best decision of my life was stopping myself from reading this manga after mujin came into the picture. I can already tell I’ll be pulling my hair out from this so I’m just gonna wait till everything is out and see how people react at the end, to see whether I’ll continue reading it lol
