Vivian Fu

The Fu Clan is cursed by a rival clan to not have a daughter. Thousands of years since the curse, the Fu family didn't have a daughter born in their family. They lost hope to have a daughter born in their clan, until Vivian is born. Everyone in the Fu Clan dotes on her and made sure that everything that she wants is given to her. Vivian is born weak, she'd get tired easily after just a few steps and she can easily get sick. A fate reader told the Fu Clan that Vivian can get stronger and live longer if she married someone who is born on exactly the same month, day, and time as her. The fate reader also told them one who is destined to be with Vivian has a butterfly-shaped birthmark on their left wrist.
