Yuki Okazaki  

Yuki is the attractive young man that Chiharu Nitta met during her summer training camp. He enjoys both city life and nature, and has many interests. At first, Chiharu dismissed him, but due to feeling lonely and arguing with Kyoichi, she almost gave in. Despite already having a girlfriend in the city, Yuki persisted in his advances and successfully won over Chiharu's affection. They spent an evening together at a scenic overlook (it is unclear if they had sexual intercourse, but it is strongly implied). Chiharu bid him farewell with a kiss that Kyoichi witnessed.
