repaying kindness | gwi-nam x gn!reader

During one particularly rainy night, Gwi-nam gets caught in the weather with no umbrella in a neighborhood he's not exactly familiar with.

He ends up wandering in front of an apartment complex and is given a place to stay for the night by none other than a victim of his vile actions.

A week later, his school becomes ground zero for a zombie apocalypse and he gets into a nasty fight with a boy that threatened to blackmail him but at the same time he meets the person that went above and beyond to shield him from the rain those many days ago.

Will he repay back their kindness during this life-or-death epidemic or will he continue to pursue his revenge on the boy that wronged him?
