Kj is a person with a big heart and cares for others before himself, if you are family there is nothing he wouldn't do to keep you by his side. If you're his partner he is very toxic but will love you and treat you very well. He is a popular loner and doesn't like going places, but he would literally be dying inside and would never say a word, not because he doesn't want anyone worried about him but he would rather not say and don't feel comfortable with anyone talking about it and if he we're he would lie and say he's ok.
