You always call him Hyeon, and he loved that nickname. He's an introvert but intelligent guy, you've been close friends ever since 1st year. You guys were inseparable.

One day, you saw 'hyeon' talking to another girl with a bright smile on his face, though he never smiled like that with you. And you felt upset and jealous, you chose to walk pass them and ignore them.

"A-Are you mad?" "H-hey.. Wait up!"
