@Edna so basically bottom (nanmu) was in love with the top's (pilgyun) mom who was actually a mafia's boss mistress... so when the boss found out nanmu got punished for it which was his own friends had to R*** him for all of life..... so to sum it up pilgyun is older now and totally in love with nanmu since he was a kid and this is his story of himavenging the years of abuse nanmu faces by killing a lot of people who hurt "daddy"
