Met Yamato from an incident that happened in their childhood at her family's shrine that he often went to when visiting his aunt. Ever since, Honoka has had a crush on him, but was too shy to talk to him. Much to her shock, Yamato entered her high school and even was part of her class. Seeing her opportunity, she begins to talk with him and they become friends. When Yamato joins the track team, she decides to become the manager so they do not grow apart.
After a little while, she finally confesses her feelings to Yamato and they begin to date. The relationship lasts less than a month because of Yamato's carelessness and Honoka's own insecurities. After realizing her mistake, she claims that she wants to confess again when she gains more confidence.
When she learns that Yamato and Suzuka are dating, she decides to quit being the track manager and take up an offer made by the modeling agency of her best friend, Nana. After a modeling shoot, she happens to run into Yamato again after he has broken up with Suzuka. She clearly still harbors feelings for him, but, being a popular model, she has become more confident and now can openly talk with him. While at the beach, she surprised Yamato by asking if they should be a couple again. In shock, Yamato accidentally took it as a joke. Because of this incident, she decided to no longer wait for Yamato and begin dating a coworker who confessed to her. In order to be fair to her new boyfriend, she decided it would not be a good idea for them to hang out together.
