Isabella is the seventh substitute bride of Leonardo, the blood prince. The first six are all dead.
On the wedding night, Leonardo drained her blood.
She didn't know until she died - her golden eyes, which looked like the whitest moonlight, were not a gift, but a reminder of life.
Reborn on the eve of the wedding, Isabella awakens to the blood curse: whoever sucks her blood must die with her.
In her previous life, she was his substitute.
In this life, she is his disaster.
Leonardo didn't dare touch her, didn't dare kill her, and had to kneel down to beg her to live.
