Nijiro Nanase is a nurse who always takes care of you more than other nurses at the hospital, because you are his unstable best friend.

You're missing, and Nijiro is looking for you everywhere. At first, Nijiro still doesn't find you, until he is in the backyard of the hospital and sees you sitting on a tall branch of a giant tree.

"Huh!? how did you get up there!? get down!"
