Chapter 18

It's a Misunderstanding (誤解なんだが) is chapter 18 of Grand Blue manga.

Summary
Iori tries to think of a way to privately practice for the remaining test portion, fearing how Kohei and Aina might react if they see him fail. Peek a Boo decides to rent a car so they can go to a nearby fish market. However, the only vehicle left that will fit them is a flatbed truck. At the fish market, Aina and Kohei overhear the others asking for lewd things, but Chisa points out they are actual names of fish. Back at the beach house, the group splits into pairs to cook dinner in shifts. Iori manages to pair up with Chisa, and asks for help on his diving practice. However, Aina and Kohei think they are dating.
