Because of their fall record, Seishu is not invited to the spring Koshien tournament. Akane wins that year's Koshien poster art contest with a painting of a pitcher that Aoba claims depicts Ko's form. Ko corrects her, saying that Akane based it on his photos of Aoba, which he had used to model his pitching style. From Akaishi, Akane learns of Wakaba's relationship with Ko. Aoba tells Azuma she will try out for the women's national team in March, and when she teases him about being given chocolates for Valentine's Day, he says the only girl he would consider going out with is her. For Valentine's Day, both Aoba and Azuma receive many chocolates. When Aoba drops Ko's chocolates off a bridge, she buys replacements, including one extra to give to Azuma for her. When Ko delivers it, Azuma says that he likes Aoba because she is hard to figure out, because she is not true to herself. That evening, Akane asks Ko to show her photographs of Wakaba. As she looks through his albums, she comments that it is obvious Wakaba loved him, and would still love him today. As she leaves, she gives him chocolate.
