[Amuai Okashi Seisakusho (Yuukey)] My Doppelgänger Stole My Life and My Girlfriend, and Turns Me into a Buxom JK

Ao's life is stolen out from under him when a doppelgänger takes his identity, his girlfriend Mio, and his male body, remaking him as a voluptuous high school girl nobody can see through. Back in the classroom, he can barely hold the secret in front of the girl he loves, and it isn't long before Mio's affection turns intimate, the two losing themselves in sweaty, heart-eyed girl-on-girl passion while Mio stays oblivious that her new lover was once the boy who confessed to her. With the doppelgänger rewriting memories so thoroughly that womanhood starts to feel like destiny, Ao is left teetering between reclaiming his stolen life and surrendering completely to the pleasure of his new body.
