Yuta, a childhood friend, was neither a friend nor a family member... nor a lover. I thought this relationship would last forever. I felt that if I confessed, this relationship would break, so I concealed my feelings for Yuta and grew up, while Yuta got engaged to another girl. On the night I was introduced to my fiancée, Miki-chan, I glanced at their sleeping faces as they drifted off together, and decided to end my long-standing unrequited love.
