Finding your soulmate doesn't always mean it's the person you expected.

Riku Hiroshi spends his days in the shadow. A skilled and lethal ninja, he is at the top of his game. The one thing, he is missing is that special someone to share his life with, but how can he when danger lurks around every corner? His carefully manicured life is thrown into chaos the day his path crosses Natasha Smith, and he saves her life.

A young teacher visiting Japan, she is taken off guard when Riku sweeps in to protect her from a gang of street thugs. Feeling obligated, she invites him to dinner to show her appreciation. It should have ended there, but a sinister man wants Riku dead and will stop at nothing to achieve this.

He deploys his best people to hunt Riku, and now Natasha, down. It is a deadly game of cat and mouse neither is sure they can survive. Somewhere along the way, they discover hidden truths and come to understand that the heart wants what it wants.

Can love win through the cultural differences before danger finds them?
