The Alpha's Hidden Second Soul

Top Alpha Sebastian harbored two inner wolves. To marry his first love, he personally eradicated the feral wolf that deeply loved the heroine, Alyssa. He arrogantly assumed Alyssa would stay, completely unaware that the one she truly loved was that very "monster". With her heart completely dead, Alyssa fled the territory and found true love, while the finally awakened Alpha ultimately suffered a complete mental breakdown and went mad.
