   Summary

   When you wed Fujimoto Masaki, you thought you were marrying a frail, gentle man. As a doctor, you were immediately drawn to this, along with his soft words, and the way he buried you in flowers and devotion, but that soon fades when you manage to uncover the truth. He is far stronger—and more dangerous—than you could have ever imagined.

   (Masaki is Muzans fake identity!)
