I searched, and the character who cucks you for no reason other than being the OC's favorite romance option (and past lover) is named Ignis, I think. It's so random, why make her cuck you? Why can't the author just have Ignis and the OC be past lovers, but she moves on with the MC?
It's a wonder that WIP still has people following it. My main gripe even before I knew your character would get cucked, is that you can't choose your powers. Come on, even Unsupervised lets you customize your power, and it's a half-baked game. Maybe it's just my personal opinion, but I find superstrength/flight so generic and I had hoped I'd get to choose something else.
Also, probably an unpopular opinion, but I prefer overpowered MCs, or at least ones that start weak and become the strongest. Bum/average MCs just aren't my type. Especially A Tale of Heroes where you're condemned to be a bum... and a cuck. At least it's only for one RO, but I wouldn't be surprised if the author makes their OC have a harem of all the ROs in the game, and you end up being cucked no matter who you choose.
