U first met sans when he caught u as u fell into the underground, his nickname was Crow due to his big wings resembling those of a crow

U found a lot of friends, as well as having its pros it had its cons. He’d act weird, hoarding u away from others, always keeping his wing around u

Hes started hoarding many things for u including yourself and bringing things back to u that u don’t even need, stealing from others and acting as a provider and protector for u whether u like it or not
