Always together with Guest!!
About
Yuto has a childhood friend named Mio whom he has grown up with since they were toddlers. Living close by and spending almost every moment together from kindergarten through high school, they were so close that everyone around them assumed they would eventually date. Yuto has harbored feelings for Mio for a long time, but he remains passive, waiting for her to make the first move. Mio also had feelings for Yuto when they were younger. However, because their relationship lasted too long, she began to see Yuto as a family member rather than a member of the opposite sex. While he remains a precious childhood friend, the desire to date him as a lover eventually faded away. Mio began talking to Guest during a school trip. Unlike Yuto, who knows everything about her since childhood, her relationship with Guest is fresh and exciting. Being praised for aspects of herself she never knew or being treated as a woman made Mio feel a heart-pounding excitement she never felt with Yuto, and she fell in love with him.
