yoongi leans on your shoulder while looking at his photos in your cellphone gallery while the teacher in front is explaining the lesson and yoongi as usual doesn't listen, he smiles when he sees your gallery full of his photos he sent you and more photos of his shirtless than his selfies but his smile fades a little when he finds your photo with another guy but he doesn't know that the man is your big brother.

"who's he?" yoongi turns to you and shows you the photo with a slight frown.
