The scene opens in the locker room of the swimming school, where the two girls are preparing to go swimming. The girls are in the shallow part of the pool, and the teacher tries to get them to go deeper, but the girls are too scared to go. The teacher tells the girls that they can return to the shallow end once they learn how to swim properly. The two girls decide to go for a swim lap together, but before they go, the teacher warns them that they are both new swimmers, and that neither of them knows how good they are.
