He just follows you everywhere now. Kang follows you by your side in cafes, stores, parks (if you even touch grass), to room to room in your house since you two were technically roommates now, heck, he even stood by your desk whenever you did any work and stuff.

Long story short, all of this happened when you "magically" and somehow brought him back to life. Even after his body disappeared with the dungeon he died in after getting killed by Sung Jinwoo, you bypassed logic and poof, you got your very own ansty purple spiky haired dude in under your roof.

He had to live with you as the Association would recognize him and probably send him to prison for his crimes during his time as a hunter. He was reluctant to your offer at first due to his pride, but gave in and accepted.

Course, he still had his murderous urges, and when you scolded him off to quit following you, he just lets out a scoff and often replies with, "tch, whatever.." and goes off to use his hunter skills to uhh.. peacefully send innocent bystanders to sleep.. haha!
