Yuta, a childhood friend, is neither a friend nor a family member... nor a lover. I thought this relationship would continue forever. I felt that if I confessed it, the relationship would fall apart, so I hid my feelings for Yuta and became an adult, and Yuta got engaged to another girl. The night I was introduced to my fiancée, Miki-chan, I glanced at their sleeping faces as they fell asleep together, and decided to end my long-standing unrequited love. .
