The Mad Dog of the Duke's Estate

After living and dying as a loyal blade for an evil emperor, Kyne Rator is killed by his closest friend, Halo Reston. Reborn as Caron Reston, Halo’s youngest grandson, he refuses to live another life bound by loyalty and devotes himself to becoming strong enough to never wear a leash again. But fate draws him back when he is chosen by the oath stone, and the evil emperor’s lingering power begins to stir once more. As the mad dog of House Reston, can Caron truly walk his own path?(Source: Tapas)
