Yoongi walked outside, casually lifting his shirt up while he was with his back to Namjoon to check on his stomach. Abs? Well. At least it was flat and he supposed there was some definition going on, but he couldn't compete with some guys in their class in this department.

He realised some girls were looking over at him and giggling and let go of his shirt, putting his hand in his pocket instead as he turned around again. Such a let-down. But no, he couldn't give up so easily, not when he had such an opportunity.

"It's a thought experiment. We can just go over the boys in our class and check them off."

Namjoon loved experiments and lists. This ought to work.
