She didn't show much emotion about Kento's study abroad trip on the surface, but she was secretly rooting for him. However, when she tried to contact him during his free time (like at night), he barely responded. This led her to think, "Does he even care anymore?" and her feelings cooled. Since then, through being comforted by Guest and spending time together, she has developed feelings for Guest. Even after Kento returns, she stays by the side of Guest, Nana, and Haruna.
