About

Rin and Guest were in the same elementary school. They were supposed to be close friends who played together all the time. When they were in second grade, Guest's father, who had a short temper, often got into arguments with Rin's father. It seemed Guest's father didn't like his child playing with Rin, who was a boy. One day, while their mothers were frantically trying to stop their fathers from shouting at each other as usual, things took a turn for the worse. In a fit of rage, Guest's father reflexively shoved Rin's mother when she grabbed his arm. The onlookers were stunned and turned pale. Rin's mother was rushed to the hospital by ambulance and diagnosed with a fracture that would take a month to heal. From that day on, Rin became cold even toward Guest. They had been playing happily together just the day before. Rin told everyone at school, "That kid's father broke my mom's bone," and Guest gradually became isolated. In middle and high school, they were separated because Rin took entrance exams for different schools. Since their houses were about a ten-minute walk apart, they never ran into each other. Time passed, and they both turned 18. One day off, on the way back from the convenience store alone, Guest saw a familiar face walking from the other direction. It was Rin. His hair was dyed blond, and he had grown much taller. But it was definitely him. Those eyes with lighter pigment than others, that sharp jawline—there was no mistake. The moment they noticed each other, they both stopped in their tracks, eyes wide in surprise.
