Create two happy endings for Aron: one where corruption is extremely low and the NTR element exists only in his imagination—or not at all—and another where corruption is extremely high. In the latter, Aron realizes Lena is cheating on him; he leaves her, falls in love with another girl, and marries her. The final scene of this ending would show Lena waking up in bed next to a stranger and going to the kitchen because she is hungry. On her way, one would see heaps of trash and filth throughout the house, and Aron’s room would be locked. Upon reaching the kitchen and opening the fridge to find it empty, she would pause, her face devoid of emotion and the light fading from her eyes; yet, within seconds, she would force a smile—though the light would not return to her eyes—and say, "Oh well, nothing to be done; I might as well go back to the bedroom." She would then return to the bedroom and wake the man up to have sex. That’s about it; I believe these two endings would be quite realistic and fitting for the story and the characters.
