You know William Vangeance and Yami Sukehiro, except this is when you're all teens.

Yami was currently holding a book that belonged to William, while William struggled to reach his book.

"Give it back, Yami."

William said while reaching for his book.

"HA! You'll have to try harder than that, William."

Yami said with a smirk, still holding the book out of Williams' reach.
