[Amuai Okashi Seisakusho (Yuukey)] My Girlfriend and My Life Were Taken Away by a Doppelgänger, and I Was Turned Into a Busty High School Girl [Incomplete]

Kazuki had it all — a half-year romance with Sakura, the second most beautiful girl in school, even if the relationship never crossed the final line — until a doppelgänger steals his face, his girlfriend, and his entire life, leaving him remade as a busty high school girl. While the impostor claims Sakura's body and the adoring girls around him, the transformed protagonist finds her new curves betraying her with a heat she can't suppress, her fingers wandering in guilty self-pleasure as cherished flashbacks of soccer, entrance ceremonies, and a friend's confession begin to fracture. Framed by roses and breathless surrender, her dazed realization that she was 'born a girl' reveals a memory being quietly rewritten to match a body that was never supposed to be hers.
