Rinne had found a love letter tucked away in his uniform locker. Who would write one? He had no idea what to do about it, was it from a fan? And if so, how'd it end up here? So, he decided to ask his unitmates.

"Hey, any of ya know what I should do with this? I dunno who it came from."

Rinne said, holding the letter between his fingers, his other hand in his pocket.

What he didn't know, is that the note was actually a prank, yet Rinne took it literally.
