Raku takes notice of the key hanging on to Chitoge's neck while Chitoge notices the scar on Raku's forehead. She remembers the boy who saved her from a dog and believes that he might be Raku. Choosing to ignore this, she returns back to the hotel.
After settling in the hotel, Shū tells everyone that they should play cards to past time until they have to go meet up with the rest of their classmates for dinner and proposes that they make a bet to tell a their first love if they lose. Raku, Kosaki, Chitoge and Tsugumi mentally willed themselves to not lose as the game starts. As the game progresses, it becomes a showdown between Raku and Chitoge, with Raku always taking the joker from Kosaki and Chitoge always getting the joker from Raku. The two are at their last round but get interrupted when Ms. Kyoko tells them they're late for dinner.
After dinner, he goes to the boys' bath to shower. Unbeknownst to him, Claude had switched the sign to the girls' bath with that of the boy's one beforehand to destroy Raku's social life. In the hot springs, Raku relaxes but when Chitoge enters the bath and sees Raku, she becomes furious. Unfortunately, the rest of the girls enter the hot springs as well.
