Haruna Yuuki
Haruna is in Kohei’s class, and is also a childhood friend of his. She has a bright personality, and enjoys helping others. She has had many boys from school confess their love to her, but she has turned down every one of them.
She is shown to be having feelings for Kouhei, but she doesn’t accept it clearly nor she denies it when the topic is brought about how she feels about Kouhei.
