Yuta, a childhood friend, is neither a friend nor a family member... nor a lover. I thought this relationship would continue forever. Feeling that this relationship would be broken if she confided, she kept her feelings for Yuta a secret until she became an adult and Yuta got engaged to another girl. On the night I was introduced to her fiancée, Miki-chan, I glanced at the sleeping faces of the two of them as they fell asleep together.
