You're an established idol at SM entertainment. He's the AOMG producer you met four years ago. You're best friends- what could possibly go wrong? 

Gray has spent the last four years lowkey crushing on you, not that you had any inkling. He's watched boyfriends come and go but he can't help it- he's a er for you. Except now it's not cute anymore. He's frustrated and you're clueless as you move on to your next boyfriend who's not Sunghwa. All He can do is watch from the sidelines as you look past him and it hurts like hell that you can't see him.
