The Secret of the Wolf Duke

To maintain his "secret," Alto only engages in dry sex, even after marrying Viviana. Viviana, deeply distressed by this and having only experienced self-pleasure, regresses in time, determined never to marry Alto in this lifetime.

Unaware of her regression, Alto, wanting to curb her somewhat emotional behavior, promises to work towards a harmonious sexual relationship...

Viviana Lorentz, the Duchess of House Fortuna, becomes utterly displeased with her far-too-rigid husband, Alto Fortuna, the duke who rarely entertains her at night. When she finally snaps and clashes with him, she ends up tumbling back in time, exactly a month before their destined marriage. Determined to escape the marriage this time, Viviana requests to call it off, only to be taken aback by Alto's firm refusal. As a final measure, Viviana decides to make a rather lustful "deal" with her current fiancé, not realizing she will end up facing his unexpected secret.
