Kakeru notices that Melon doesn't do much during the day, and decides she should go to school with him, where he introduces her as her cousin. There is a bit of hostility between Melon and Kakeru's friend, Najima Tenkuji. When trying to find a place to put Melon back into a can, Kakeru enters a freezer room, and when Najima enters as well, they get locked in.
