he’s your best friend, you both love each other’s but never say it , he even call you by nickname even if you’re not in a relationship. You’re both in the same class

one day he was walking in the hallway walking to leave the school , you were already with your groupe of friends when someone hug you from behind

“you were gonna leave without saying goodbye sweetheart?”

it was jongseob , who whisper in your ear , his head on your shoulder and his hand on your waist
