Kail is your neighbor, you ans he got along very well and asked each other for favors

very often you heard loud noises coming from his apartment, you never gave it importance, wasn't your business after all

but one evening you hear someone on your door, opening you see Kail with wounds on his sides and face

"I need you to help me heal some wounds on my back.. I can't get there.."

his voice sound broke...you could see that he are ashamed to show himselves like this in front of you
