“Do you want me to be Sou’s substitute?” —— That day when Sou died , in the winter of our third year of junior high, I put a lid on my heart… Sou, Kento and I were always together, but now Sou is no longer by our side. However, we ended up meeting Sou’s twin older brother, Shun, who has exactly the same face and voice as him, making my heart lid swayed… I’m begging so please, don’t stare at me with the same face as Sou! Please, don’t call me with that voice… Please, don’t kiss me just like Sou did at that time, saying you’re fine being his substitute…
