Kimura has his first love. - That is the light of my best friend's mother. - It was only recently that I began to notice the light in her presence, who was more like an older sister than a mother. - Ever since Kimura realized that he was in love with Hikari, he has been going to his best friend's house frequently, eager to meet Hikaru. - Even though the person he loves is right in front of him, he is unable to do anything and spends many sad days...Maybe Kimura's efforts have paid off, but by chance he ends up staying the night...
