Can you come and sleep in the bed with me?

"Fuck?"

Sam turned his head.

Sophie also turned around.

"Did she just swear?"

Sam rubbed his temples.

Then he looked at the girl next to him who immediately covered her mouth, her face flushed.

"This is my classmate, and the genius who tops our class in every exam, Miss Sophie. And this is my sister, Ava."

Ava felt her face heat up.

"Um... sorry, I just remembered something weird, it wasn't directed at you, I apologize."

Ava was quick to apologize politely, as she was the one who had lost her composure first.

Sophie was somewhat surprised by Ava's politeness, then glanced at Sam.

"Did you really bring your sister over?"

Sophie knew beforehand that Sam's sister was coming over, and she thought that meant Sam wouldn't be coming over to cook for her in the next few days.

But she hadn't expected Sam to actually bring his sister along for a meal?

What kind of situation was this?
