I'm seriously more scared of him NOT killing Leewon... Making sure he doesn't die, so he can keep toturing him...
Gosh, Leewon lost his beloved mother, had to meet his bio father who is also an immoral scheming mafia boss, got manipulated/betrayed by that bas**** old fox, and now this crazy a** crime lord bi*** is raping him... He was attached to him too, which makis this even more hurtful... Leewon just wanted to live a clean life and help people. FK all of them.
