i know i'm biased af cuz i'm han-seo trash but hear me out. I think Han-seok's plan in ep 20 should've been more about Han-seo. Han-seo's betrayal hit him Way Worse than Vincenzo getting the woman he had a crush on (it didn't even seem that deep), especially considering Han-seo basically replaced Han-seok with his worst enemy. idk i just think they should've gone harder on the whole "you stole my brother" thing. Cha-young could still have taken a bullet for Vin, but not so bad that she couldn't see this plan through at Vin's side (yes I still think Vin should've let her have Choi Myung-hee, that was her archenemy, this revenge should've been hers)
