Marry Stayed Out All Night - FL is promised to ML2 so she pretends she is married to ML1. Iteracts with both but ends up with ML1.
Marriage, not Dating - main leads are voluntarily in contract relationship. Cute guy appears and FL falls shortly for him.
Because This Is My First Life - main leads are (voluntarily) in contract marriage but dont love each other. Cute guy appears and FL falls shortly for him.
See them, but thanks.
Also when does that happen in Because this is my first life?
The first guy tried to rape her and it didn't seem like she liked that guy who they thought was stalking her.
