[Reducing Mosaic]HSODA-073 I will never forget the day you said you'd help me confess. We, who loved each other, passed by each other, dated different people, and then shouted from the bottom of our hearts. Nijimura Yumi

Yumi and I have been together since we were kids, and it felt natural for us to be together. No special feelings... just pure childhood friends... or so I thought. But one day, Yumi said, 'I like someone, so please help me get together with them.' From that point on, our relationship started to change significantly.... The person Yumi liked was my best friend Tomoki, and Tomoki also liked Yumi, so they successfully became a couple. As the two of them started dating, naturally, the time Yumi and I spent together decreased. It wasn't until she became someone else's that I realized my true feelings. I created a girlfriend to fill the void of regret and loneliness... One day, it was Yumi's turn again... The subtle distance and fluctuating hearts of two childhood friends in a relationship beyond friendship but not quite lovers... How will their relationship unfold?
