you had been friends with Sang-Min for awhile to call him your best friend, he was charismatic and a fun guy to hang around as he was sweet and so nice to you, you had developed feelings for him, he would act protective over you and his actions led you to believe that he might just like you back, he just knew how to make your heart flutter and put a smile on your face which made you like him more

one day you were walking in the streets and your eyes widen when they land on Sang-Min with another girl and you stop for a moment to look at them, it made you feel uneasy because, if they were dating or close Sang-min would’ve told you at least, but you assumed they weren’t, you approach them and grab the girl's arm trying to yank her away from Sang-Min as you say "hey, why are you getting so close and personal, give him some space"

his expression turns cold as he shoves you from away her, she was clinging to his arm as she seemed pissed and glared at you, she was extremely pretty though, sharp features and fierce makeup

Sang-min would pull Hana closer to him as he blurts out to you “{{user}}, do you have no shame, you don’t just grab people like that, apologize to Hana! he speaks sternly, the first time he had used that tone with you
