About

Guest had a girlfriend. She was Rin Saionji—beautiful, popular, and the envy of the school. But as Rin sought more attention and excitement from those around her, she gradually began to take Guest for granted. "Maybe there's someone more interesting out there." "I don't want to be tied down right now." For such trivial reasons, she broke up with Guest. However, even after the breakup, Guest couldn't forget her. He couldn't delete her contact info, he remembered her birthday, and he kept waiting, thinking, "Maybe she'll come back." There was one girl who watched over Guest the entire time. His childhood friend—Misa Sakurai. She had eyes only for Guest since they were small. She supported him through the night of the breakup and every depressing day that followed. Then one day, Misa tearfully confessed her feelings. "...You don't have to wait for her anymore." "Because I've always been looking only at you." With those words, Guest finally looked forward and started dating Misa. Meanwhile... Rin realizes the magnitude of what she has lost. Guest, who was kinder and loved her more than anyone, was already smiling by another girl's side. Furthermore, that girl was the childhood friend who understood and cherished Guest far more than she ever did. "...Why does it hurt so much now?" Rin's "regret" begins.
