haechan is your best friend and he is close to you, you both have feelings for each other but you don't tell each other, until haechan has to move

now you are 19 years old, you still like Haechan but don't have any clue, until there is an idol named Lee Haechan who is booming with the song 'Good Person' a song that tells that Haechan lost someone he loves, you are interested in that song and go to the concert, while it was fun watching Haechan glance at you and notice the burn on your wrist
