Dongwoo always has something in his backpack that was stupid. Kids' toys were in a 20 year old's backpack! Even Sungyeol the choding laughs at him! One day, after accidentally bumping into a girl, he finds four rubix cubes in his backpack. All different from each other. 

They were all unsolved, but looked like they were solved many times before.

"Oooh, hyung, do you know how to solve that? Especially that big one!?" Sungjong asked.

"No Sungjong, I accidentally took this from a friend. I'm going to return it as soon as I see them again," I said as I put them into my back pack.

"Hey, that one has something in the cracks,"L said and took the 3x3x3 cube and took out a small note,"Call ***-***-**** if found."

"Call it Woo,"Sunggyu said as he sat down next to me on the couch while Sungjong tried to solve the 3x3x3.

"Hello?" A voice asked annoyed.

"Hello? I have some rubix cubes. I think I accidentally took them,"I said.

"Ah! Yeah, you took my cubes. And I have your phone."
