who is the lamb and who is the knife

Boong-do: I said I’d take care of you… I appeared suddenly and entered your life, caused chaos for you, to only be your boyfriend for a short while, or buy you an expensive car, or even spray water at that person [Han Dong-min].

Hee-jin: It’s an excellent conclusion.
