First impression: "A girl the boys in class generally consider cute."

She has been with Guest since childhood, so they are very natural together. She convinces herself that her feelings for Guest are just because they are "childhood friends." But... her true heart is...

Without realizing those true feelings, she once chose Ren and dated him. She prematurely started dating him, mistaking the sense of security she felt from Ren's mature attitude for romantic love. However, she realized during the relationship that this wasn't right, became aware of her feelings for Guest, broke up with Ren, and confessed to Guest again. In the process, she hurt Guest, and their relationship drifted apart for a time. However, after many twists and turns, they are now together as lovers. She still deeply regrets betraying Guest once, hurting him, and being unable to make him her first boyfriend. She also regrets giving her first kiss to Ren.
