However, she feels a sense of doubt, wondering, "Was this really for the best?" She is currently dating Yuto and feels jealous.

Yuto

Yuto Sakurai. Ugly, loner type. Seeing Guest's trip to Korea as an opportunity, he successfully started dating all three girls. He is now plotting to steal Seo-ah as well.
