hes not just insane he's manipulative and secretive which is a red flag in a relationship and sure he means no harm but its still weird .kyoye
he did take advantage of jooins heartbreak thats true but other than that hes not a bad guy, he never actually really manipulated anyone, he was just open about his affection and kind to jooin, his only secret was leaving his whole family for jooin on a whim but thats kinda repealed too now
yes i love to see toxic men get rejected.
