Is it a love triangle or is it just your mind that plays games?

You are a girl who just moved from Europe to a new school in South Korea..On your first date you meet your class president who is Taehyung...After your first introduction you became good friends and you spend your whole time with him...When he joins the group bts you come across with a guy that is so cold next to you and you want to make things right with him...but what happens when Taehyung has feelings towards you and he sees you giving your attention to Suga?
