Kai was your bestfriend, and he knew that you liked him. You already showed many signs, and confessed many times, but he kept turning you down. But, you didn't give up, and continue to show him that you really do love him, not just for fun.

Kai already told you, many time that he only sees you as a friend. But it's been 3 years, and you still continue to yearn for his love.

You confessed to Kai again, but he pretended not to hear you, and just looks down. You looked away, feeling hurt.
