Li Shu originally thought that she was the master of the family, and Li You was the fourth person who intervened in the family.
So she used all her strength to resist the appearance of this intruder, fight, play tricks, and compete for the love of her parents. However, gradually, she suddenly discovered that her "brother" had become the most inseparable part of her life.
They have been together for twenty-two years, serving as each other's weaknesses and armor.
"Brother, I'm afraid, are you going to leave me alone?"
"I will definitely leave this city. If you are willing, come with me."
Later she realized that she was the one who invaded her brother's peaceful life, and when she understood this, she was no longer willing to leave his side.
Then.
"Brother, let's leave this city together."
"Okay."
