is that it?, is seongbin really the killer?, idk... maybe i got my hopes to high...i just expected for a mindblowing plot twist on who's the killer, i guess tge only thing we have to find out is the reason of the murder... but idk why, with all the gathered evidences that is clearly related to seongbin, something in me tells that it's not him...ughhh it's those mind blowing plot twists movies that ive watched(that's why i expected more from it)
