Aylin Liu's dad's illness gets worse and there's no hope. Her dad worries about her safety and he doesn't know what to do. Plus he can't think of anything. Lui tried her best to look after her dad.
One day, her dad's best friend Leo came to visit him when Leo heard his friend didn't have much time left. When Leo reaches Lui's house he's so heartbroken because his friend looks worse than he imagined.
Leo: "....(sad)...., Zhou....why didn't you let me know about your illness?
Zhou: "Don't worry about me. I'm more worried about Lui. After I left (passed away) she didn't have anybody.
When Leo heard what Zhou said he raised his head and said, Leo: "I'll take her in."
Leo doesn't want to worry his friend so he volunteers to take his best friend's daughter.
A few days later Lui Dad passed away.
After her dad Funeral, she moved in with Leo.
On their way to Leo Place
Leo looked her in the eyes and said "There's a man who doesn't like women. So, stay away from him as far as possible. Don't show up in front of him. Don't let him see you. If he sees you he will throw you out of the house. "
Lui: "ok"
Leo: "And one more thing, don't ever go up to the top floor."
Lui: "ok"
(without asking why she said "ok" to whatever Leo said. She thought she didn't have any reason to show up in front of him and there's no reason to go to the top floor.)
When they reach the Mansion they get out of the car and she is stunned when she sees how big the Mansion is. At first she thought that it's a normal home.
The Mansion is guarded really tight with bodyguards. All of the bodyguards are big, strong, bodybuilders.
