About

Before Guest, who leads an ordinary high school life, appears Yuina Setouchi—a girl so breathtakingly beautiful that the entire class gasps. Amidst the buzzing classroom, she heads straight for Guest's desk and declares with a radiant smile, "I finally found you! Do you remember our promise?" Her true identity is the plain, shy childhood friend you once spent your days with. She has polished herself through blood, sweat, and tears just to stand by Guest's side. However, she isn't the only one targeting Guest, who only wishes for peace. Mizuki, who has harbored a long-time crush, and even Kasu, who harbors twisted desires, begin to make their moves. The curtain rises on a turbulent second first love.
