This world was a sh*tty place. And I was a minor character who got his girlfriend cuckolded by the main character. So, I didn’t go against the game, but moved as the game was set up, and finally the main character stealed my childhood friend’s girlfriend. Now I can freely fall in love. That’s what I thought. But it seems that I have a problem with my ex-girlfriend ……. This is a story where I, a supporting character, surpassed the main character.
