During middle school, Seko Rento fell in love with his classmate Yosaki Misa, who had once saved him. Rento, who went to the same high school as Misa, repeatedly made bold advances toward Misa, but all of them were unsuccessful. However, Rento never give up. Such days continued for about a year. Today, as usual, Rento confesses his love to Misa, and Misa’s best friend, Hinata Haru, always gets in the way of Rento to protect Misa. Yet, the three of them often chatted normally, and they also often went home together. On the way home, Rento sits on a bench in a nearby park after parting ways with the other two at a crossroads. After a short while, Haru who was supposed to have left arrives. “Well then, let’s go to my house again today.” This is the story of the three of them.
