Deb in NIF is not scarred as far as I can tell. She just guarded. Always wanted to be in control and idolized. Tough. She has not even done any whipping or pain stuff in my save files. She just wants you to pamper her and tend to her needs while addressing her as an authority figure. Slowly working her way up to bondage and maybe some humiliation or painplay. But for the most part she is a women bored with most vanilla sex. If not all. The villain of the game is KIM. Not DEB. Deb is just bored with her sex life with her lover but still loves him as a person. They try an open relationship and she asks the MC to be her sub. That's then is up to you where that goes. She dommes you now and then and you can let it escalate or take it slow. KIM on the other hand is a bad girl character is dabbles into sociopathic traits. Wanting to be the winner and sneaky all the time. Using double talk and lawyer level blackmail to trick people into situations. She cheats often but never gets caught. The MC chooses to be her minion and let her use them or tell on her or stay out of her love life with his best friend.
