After accidentally kissing Tsukasa Domyoji at his party, Tsukushi Makino stares back at him in shock. She runs to the deck of the ship, where Tsukasa says, "Don't tell me you've never been kissed before?" Obviously upset, Tsukushi tells him "Don't come near me!", when he steps closer. Tsukushi feels foolish about the whole night and believes that kissing Tsukasa was her "punishment". She returns to Kazuya Aoike's villa and tries to fall asleep, only to imagine kissing Tsukasa again.
The F4 and Shizuka Todo visit the beach the next day, but are gawked at by the other beach-goers. Tsukushi's mother wishes her to see Tsukasa and drags Tsukushi to the beach, despite her protests. Akira Mimasaka and Sojiro Nishikado tease Tsukushi and Tsukasa about their kiss. Tsukushi looks to Rui and denies the kiss, though he coldly brushes her off. Later, Kazuya challenges Tsukasa to catch more cuttlefish than him, while Tsukushi goes to return Shizuka's dress.
On the ship, Tsukushi stumbles upon many of her classmates in intimate situations, while trying to find Shizuka's cabin. She then overhears Shizuka and Rui on deck. Shizuka casually asks Rui, "Well, you like [Tsukushi], don't you?" The statement angers Rui, who launches into a rant about Shizuka. He tells her, "There's only one girl I want," before dragging her into one of the ship's empty cabins. Tsukushi's legs give out from under her and she drops the dress as tears start to form in her eyes.
