MTL - Tome of Blood - Chapter 4 -4- I became a vampire?

At home, she was invisible; after marriage, she was a decorative vase; in the end, a sea of flames buried her, and not even her corpse remained. This is the portrait of Han Yuxi’s previous lifetime.

Given a chance at rebirth, she strives to improve herself, wishing only to no longer serve as a foil or a pretty face. Then, she will seek out an exemplary husband and live a life of peace and prosperity. Alas, things turn out contrary to her wishes—she marries a man who bears a blood feud and hatred as deep as the sea.

She turns the world upside-down, but her road to happiness is strewn with setbacks and the sweetness that comes after bitterness.
