That Gucci

"So, you're telling me that your boyfriend in that picture is THE INNOCENT KIM TAE HYUNG from BTS?"
"Duh!" Wait, who?
Being single all your life, you faked your relationship status as 'dating' in order to fit in with your schoolmates. But when your so-called friends suspect you of not having one, you did the impossible. You snapped a photo of a random boy, and claiming him to be yours.
What you are unaware of, is who he really is and the fact that he studies at your school didn't help either. Slight AU
Story is loosely based on Wolf Girl, Black Prince.
