mangaupdates.com had this to say:
From Lezhin:
Most outcasts are ostracized because they look different, talk different, or live different. But not everyone. And not every previous outcast turns into a revenge machine. After seeing his friend suffer a horrific incident, the once outcast, Kang Haneul, decides to exact revenge with the help of an ability he never knew existed. https://www.mangaupdates.com/series.html?id=131944
A guy was being bullied, the guys that bullied him also hurt his best friend, the guy wanted to become stronger for her and now whenever he takes his glasses of he becames a fighting beast, but he must get stronger to get his revenge...
