Kris is a cocky , he gets angry easily but doesn't show it really. He can be sweet but only when he is comfortable with someone. You don't want to get on the bad side of his especially when he is hurry or in heat 

Sunggyu- Kris and Sunggyu were best friend when they were younger due to Kris finding the younger wandering about in the forest, he helped Gyu home and from then on they meet in secret and become best friends but due to Sunggyu's father being a beast tamer he didn't like his son hanging around a beast and so when he found out he threatened the younger saying that if he didn't stop meeting his beast friend then his beast friend would end up dead and so that was the end of Kris and Sunggyu's meetings as a young. years past and Kris had stopped going to their meeting place in hope of meeting his old friend again. One day during Kris's heat he stumbled into the Ruins and upon a fae, with his burning becoming worse he went after the fae only to find that it was his old friend Sunggyu and so started a new chapter in their friendship.

Hakyeon- Kris and Hakyeon didn't start out great, Kris i need to satisfy the burning Hakyeon in a alley way when the fae had come out from work, Hakyeon had said the words that Kris hated the most but was to used to 'i hate you' Kris felt bad for what he did but what exactly could he do now?....
