His hyungnim worked with dooshik (that guy) and were very close he helped him a lot and fell in love with dooshiks sister that's the simplest answer for that . From what I remember yuta was never seen in pearlboy but if you do have the time pearlboy is such a good read!!
Basically dooshiks needed the blonde boss's help with gang stuff to avenge pearl boy and get rid of his abusers
And in so the blonde boss met dooshiks sister and from there they fell inlove
I think the mc hates dooshiks bcuz he was the reason the blonde boss is retiring/marrying and leaving him (since he is inlove with him)
And i dont blame you for not continuing pearl boy it gets pretty shit and Lowkey unreadable after season one
I know ppl say no need to read pearl boy (tried, did not like the main couple in), but I feel pretty lost even though I'm only in the first chapter?? Why is Mc blaming that guy for making his hyungnim quit? Who's yuta and why is he being a fucking cunt?
