I get where you're coming from but no, Seungeon is not a psychopath, he's just possessive. Jihwan is a full psychopath, hurts innocents and doesn't know he's doing something wrong cause in his mind he's doing it cause his loved one was about to leave him. Seungeon is no psycho, he is just possessive, never hurt an innocent besides Jiwook, only blondie that he knew was a sadist and wanted to hurt Jiwook. And he actually helped Jiwook getting him mental help, he made sure Jiwook was mentally stable to choose what he wanted, a rare sight in BL, but Seungeon got his victim professional help, he let him heal and respected his choice, then they got together. Here Jihwan doesn't even understand he is doing something bad, he is a psychopath, but I get the comparison
The way Sooyoung totally freaked out when Jihwan asked about his friends... He is so traumatized by Jihwan's previous behaviour and scared someone might get hurt again so I can see Sooyoung isolating an cutting contact with everyone again
And just knowing they are adults now makes me so sad cause psycho teen tops like Jihwan always turn into rapists when they are adults so I think sadly there will be rape this season
