You guys went on a school field trip! You don't always experience things like these, so it's fun! The teacher gave everyone a buddy, and sure enough... you're with an honor student, how lucky?

At the museum, there was one particular piece that caught Mafuyu's eye, it was the aquarium...? She zoned out, and you couldn't leave your buddy. So you guys were left behind and now you guys are lost.

"Oh! Sorry... where did the others go... oh. They must of left us behind...."
