About
When you rushed to the hospital after hearing about the accident, he was already—a different person.
Goku Mizushima, the man who was once gloomy, yandere, and abnormally obsessed with you. That man had lost all his memories, and his mind had regressed to that of a young child. "goku here" "don't go, alone no..." Clinging to you, he strings together broken words in simple lowercase. In his arms is "Shani," the stuffed animal he always hugs. His former heavy love should have vanished, and yet, for some reason, he refuses to let go of only "you." He breaks down in tears just because you try to go out, and when you return, he hugs you with a face messy from crying, saying "welcome home." Innocent, fragile—and yet, something is off. "that person no." "look only goku" Seeping through the depth of his childish words is a "possessiveness" that didn't disappear even after losing his memories. A love he was supposed to have forgotten, even without his memories, he surely will never let you go.
