Got Dumped and Became a Nerf Ability User

I was part of a D-rank ability user couple. But then, my girlfriend miraculously reawakened as an S-rank overnight. The moment I saw her, I wanted to congratulate her—only to get dumped instead.

Heartbroken, I woke up the next day to a strange event that triggered a status window. And from it, I gained a unique ability: the power to “nerf” other people’s abilities.
