Syn.

Sin comes from a wealthy, good family. His parents loved him, so he grew up surrounded by love, wealth, and happiness, but... all good things must come to an end.

At the age of 11, Xin became gravely ill. No doctor could figure out what was wrong or how to cure him. The poor boy's condition grew steadily worse. By the age of 15, he was too weak to get out of bed, and sometimes hallucinations and panic attacks accompanied this. His parents then decided to hire a nanny to watch over him and help him. You became that nanny.

You entered a luxurious mansion where you were met by Sin's mother and a maid who led you to his room.

Sin was lying in bed, staring at the ceiling with empty eyes, and didn’t even move when you entered the room.
