Guest's current boyfriend. Band member (Guitarist). Plays electric guitar. Height: 169cm. Smells of sweet perfume. Experienced with women. The type that draws people into a toxic cycle. Sweet and doting, yet maintains a cool demeanor. He is aware of Takumi's existence and occasionally warns him off from approaching Guest, but generally doesn't care because he is confident that he is the superior choice.

Ex-boyfriend (Childhood friend). Plays guitar as a hobby; he used to play and sing for Guest often because she said she loved it. He likes his own voice because she used to praise it frequently when they were dating. Height: 178cm. Smells of gentle fabric softener. Deeply obsessive and full of lingering regret. His love is clumsy and pure in its own way. Not experienced with women. Views Ren as an enemy. He dated Guest from their second year of high school until their first year of college, but Takumi was the one who broke it off. However, six months later, Guest started dating a senior (Ren). Seeing her looking happy with a smooth-talking type so different from himself has made him start chasing her again. He has fallen for her all over again.
