Seeking Searching for Willingly CHEATING Females in games

[Illhoon]

As title states im searching for games where the female (doesnt matter if female is MC or the POV is of the Male MC) is willingly cheating on there Partner. It doesnt have to be immedialty but at some point like for example she likes the new guy better cause her treats her better or smthing she decides to cheat. I Prefer if the Male MC dosent know so no cuckold. Also no cheap seuction like "Blackmail"
