Umareru Kachi no Nakatta Jibun ga Anna no Tame ni Dekiru Ikutsuka no Koto

Kazuya Mukai is a thirty-two-year-old aspiring manga artist whose life has been defined by failure, disgrace, and humiliation. One night, while lost in a drunken haze, he accidentally plummets from the rooftop of his childhood elementary school. However, instead of meeting his end, Kazuya awakens to an impossible reality: he has been transported twenty years into the past, inhabiting the body of his twelve-year-old self as a sixth-grade student. Armed with the memories of a lifetime squandered, Kazuya views this miraculous second chance as an opportunity to rewrite his tragic existence. Above all else, he resolves to change one specific part of his past—winning the heart of Anna, his first childhood crush. He believes that by pursuing her now, he can finally find the meaning and redemption that eluded him as an adult. Yet, despite his earnest intentions, Kazuya’s desperate devotion sets into motion a devastating chain of events. What begins as a pure attempt to reclaim lost time and experience a fleeting childhood romance gradually spirals into an entirely new tragedy. His innocent affection ultimately defiles the very bond he sought to protect, transforming a love that transcended time into something deeply broken.
