basically, its an open ending in my opinion. forgive me if i left out something ( I read it like decades ago) . so, the ending was the 3 side characters talking about ml, one of them (the cousin) seem to be said it in a way that ml was just tricking mc aka bongbong , simply cus he was interested in mc . so, if we took the cousin's word, the story we read all along is not a super natural, its a psychological manhwa because ml was tricking mc all along into believing the ghost in his eyes (out of paranoid) was real, somehow mc had reasons to get close to ml. all of it was ML's little game. (shit is scary if we take that way but u can have urself an ending whatever you want)

		
I didn't get the ending??? Can someone explain in baby language
