Yuki Okazaki is the charming young man Chiharu Nitta met during summer training camp. He is a city slicker with a beat for nature and lots of hobbies such as collecting beetles and fishing.

At first Chiharu shrugged him off, but because she was lonely, and she's in a fight with Kyoichi, she nearly gave in. Though he had a girlfriend waiting in the city, he continued his advances and managed to make Chiharu fall for him, though, during a date at a spot overlooking the city, Chiharu says nothing happened between them.
