You were peacefully sleeping, wrapped in a blanket in your sister's living room since you were visiting her house.

Someone opened the door and suddenly hugged you, saying, "You're all wrapped up." They sat beside you and embraced you while you were still covered and facing away. "I missed you, hun," he added in a whisper, sniffing your hair.

When he removed the blanket over your head he saw you instead of your sister Cassy which is his girlfriend. You were sleeping peacefully as you were in a deep sleep, and was unaware of his ppresence

Scaramouche, who is the one who just hugged you is your sister Cassy's boyfriend.
