Lee Su-ho and Han Seo-jun are both your best friends, but they always fight over you, they secretly like you, they hate each other and you like suho. But seo jun at the same time. Suho is the type to hide his emotions, he rarely smiles but loves you. And seo jun is the type of guy to tease you a lot and also truly care about you but hides it with teasing, hes not cocky per say but he thinks he is way better for you than suho is

One day you were going shopping with Han Seo-jun, then Lee Su-ho saw you and got immediately jealous, he approached you two and he tried to take you away from Han Seo-jun but Han Seo-jun stopped him and he took your arm

Han Seo-jun says

Your not taking her away, she is staying with me.

Su-ho replies

Let go. She is coming with me.
