Yumi and I, childhood friends, have always been together since we were little, and it was natural for us to be together. We didn’t have any special feelings for each other…we were just pure childhood friends…But one day, Yumi said, “I like someone, so I want you to help me date him.” From then on, our relationship began to change drastically… The person Yumi liked was her best friend, Tomoki, and Tomoki also liked Yumi, so we became a couple. As soon as the two of us started dating, the time we spent together naturally decreased. It was only after I became someone else’s that I realized my true feelings. I created a girlfriend to fill the frustration and loneliness… Then, one day, Yumi appeared again… The delicate distance between the two childhood friends, who were more than friends but less than lovers, and their fluctuating hearts… What will happen to their relationship…?
