I will never forget the day you said you should help me confess. We were in love with each other, and we passed each other, dating different men and women, and cried out from the heart.

My childhood friends, Yumi and I, have always been together since we were young, and it has become common for them to be together. He doesn't have any special feelings... he's a pure childhood friend... But one day, Yumi said, "I like someone so I want you to help me out so I can date you." From there, our relationship began to change dramatically... The person Yumi likes is her best friend Tomoki, and Tomoki also liked Yumi, which made the couple a great success. As the two began dating, the time spent together and Yumi naturally decreased. I realized my true feelings only when I became someone else. I created her to fill my frustration and loneliness... One day, Yumi...the subtle distance and shaking heart between two childhood friends, who were more than friends but less than lovers... What will happen to the relationship between the two?
