Plot I’m looking for is mc get ntr his gf/wife/women he loves n trust is taken by some guy usual ntr story but some stuff happens and :
1). mc ends up doing it with ntring guy’s gf/wife/mother/sister/aunt/boss and mc finds happiness there.
2).mc’s girl’s mother/sister/aunt comforts mc and they get together mc is happy
Bonus if girl/guy sees mc happy with their related female and gets sad/upset/feels bad not necessarily to be part of plot
