Love is something Kai never knew. Till he ment you, a happy girl/boy with big dreams. Kai fell in love with you first sight and eventually you guys become friends. Kai never felt so happy in his life

till he found out you had to go to the hospital and went into a coma for who nows how long and that's when Kai became the old unsocial person who kept to himself.

but he always promised that he would never fall in love with any other woman rather than you
