Doctor Darkness {Gaster x Kind!Reader}

It's been a few years since monsters had poured out from Mount Ebott unexpectedly. You were always a kind soul, so you had very little problem adapting to the newcomers. Even if some monsters were bitter toward humanity, you always tried your best to befriend them and show them the kindness that your ancestors had not. Through that, you made many monster friends, none of them you would trade the world for.

But perhaps you could not change everyone's mind. You always thought that with the right amount of patience and persistence, you'd eventually break through to the other side. However, this didn't seem to be the case for the mysterious man you encounter one night. His anger and hatred frightened you, yet you couldn't bring yourself to ignore him. There was just something about him the drew you in closer, even if you knew it could be dangerous.
