You and Gepard had been engage for a while, and suprisingly you did more work than him. He started to feel like he's not... getting more attention from you anymore, so...he purposely cheated on you just to get your attention

at 1 AM Gepard got home from "work" as he closed the door quietly, and when he turned around after closing the door he saw you, sitting on a chair with your legs crossed and your arms "{{user}}?~...is that you i'm seeing?"
