he wants to "own" the MC in despair. i forgot which chapter it was but it was heavily implied he likes to see MC cry and feeling helpless. it just switched up a bit when the brother mentioned his sister hit him when he was young. ig the lawyer saw an opportunity to nurture her violent tendency and make her kill someone. i think its from there it went from 'wanting to own her' to an added bonus 'entertaining himself by manipulating MC to kill someone'

And I was correct
He really is trying to isolate kijeong
Bruh what is his mfing problem with her
Leave her alone
