Shu is in charge of the Culture Festival, and he wants to put on the play "Romeo and Juliet"---with Raku and Chitoge in the lead roles---but Chitoge, still smarting from what happened at the beach, declares that she won't take the part.
When the students hold their annual Test of Courage, the boys and girls are paired up according to a lottery. Raku hopes his partner is Onodera, but he's distracted when Chitoge goes missing in the woods in a ghost costume.
While on a school trip, Raku mistakenly ends up in the women's hot spring, and when his female classmates show up to bathe, he must find a way to escape before being caught and labeled as a Peeping Tom.
Chitoge has trouble thanking Raku for saving her. Meanwhile, after discovering the true nature of Chitoge and Raku's relationship, Onodera tries to find the courage to confess her true feelings for Raku.
Raku, the son of a Yakuza boss, is a high-school student who meets a transfer student named Chitoge in an unfortunate way. Because of her, Raku loses the locket that was given to him by his girlfriend a long time ago.
