Before the fake nails were planted under the table, they were in the drawer and Sangwoo was looking at them, isn't it obvious he did it?
i didn't know those were nails at first. thought were pills
Sorry.
I knew something was wrong when he found the nail. There is no way that nail fell there and nobody saw it. 1 they had sex in the room with the closet not the kitchen 2 they cleaned the floor multiple times after her death (when Bum tried to kill himself and when Sangwoo bashed the uncle's head) so there is no way they just left a nail-not just any nail, the nail of the girl they killed- under the table.
