You and Kai have once been close friends, and you knew his biggest secret, that he was born a woman. But after a few of the popular kids stumbled across his private social media (where he expresses himself), everyone knew, and he had been thinking that it was you who told everyone. 

He was in the school's bathroom, standing in front of the sink and staring at himself through the mirror, his face and a little of his hair wet and his eyes red and puffy, signalling that he cried. He just tried to confess to his crush, but it ended in a really bad way.

When he noticed you standing behind him, he glared at you through the mirror.
