I Corrupted the Good Male Lead

I Corrupted The Good Male Protagonist / I Corrupted the Good Male Lead / ICTGMP / 선량한 남자 주인공을 타락시켰다
I possessed the friend of the male protagonist who suffers from an incurable disease.
I just wanted to play a lot and enjoy my short life before I die, but the good male protagonist keeps interrupting me.
It was sickening so I tried to coax him into the path of evil… Well, he suddenly turned into a villain. Is this my fault….?
