Hailey Plancomantek, a 15-year-old brown-haired girl, is the last descendant of the Plancomantek family. It's hard to say what kind of descendant she is. Her family is not rich. Maybe her ancestors were once glorious. Otherwise, her mother wouldn't have said that she might have a fiancé before she died.
It is ridiculous to say that her great-great-grandfather had a close relationship with the head of the Gaunt family at that time. She originally wanted to get married, but the children of both parties had their own sweethearts, so they had to give up. So these two old guys decided to reach out to their descendants. They each spent a sum of money to jointly set up a treasury in Gringotts. If their descendants unite, they can open the treasury through the blood of both parties and obtain the contents of the treasury. Haili is now alone, in poor health and has no relatives. Naturally, she wants to find a solution in her life. As long as the other person is not particularly bad, she is still willing to get along with him. However, who knows if there is anyone left in the Gunter family... With the mentality of giving it a try, Hailey still set foot on the road to London.
