|橋野 リナ||Hashino Rina|
|Manga Debut||Chapter 1|
Rina is described as very cute by a lot of people. She is slightly shorter than Yuki.
Rina and Kido get into a relationship at the beginning of the manga, after he confesses to her. They break up after a small fight because he didn't text her good night like he promised, but quickly get back together with the help of Yuki.
Yuki Machida Edit
Although Yuki was jealous of her at the start as she also liked Kido, they later become friends. Rina sometimes gives Yuki relationship advice and helped Yuki to realise that her feelings towards Naruse were love.
