Chihaya is still lost in the clouds after Arata confessed his feelings to her, making her unable to concentrate on studying for her exams. Kanade and Sumire, who happened to overhear Arata's confession, are debating whether they should tell Taichi or not. In the midst of all this, Chihaya gets a phone call from Sudo, who says someone in his college karuta club wants to play a match with her.

Taichi has seemed down since he lost to Arata. In fact, a dark cloud is hanging over the entire karuta club because final exams are coming up. To break out of the gloom, Chihaya, Kanade, and Sumire decide to make Valentine's Day chocolates for the club as a surprise. Chihaya has no experience with making sweets, but she gives it her all in hopes of bringing a smile back to the hard-working Taichi's face.
