Impostor Sister Weds into a Rich Family

I hadn't seen her all night.

And when I bumped into my sister at the dining hall, there was a strong salty smell emanating from her.

Suppressing my nausea, I took a gulp of water and went upstairs.

But I couldn't help but utter a few words when I caught a glimpse of her being scantily clad.

"Mom and Dad don't like it when you stay out all night. You should be more careful..."

Before I could finish, there was a loud crash.

I was startled.

Turning back, I saw that she was still hungover, and the glass in her hand had collided with the edge of the table, shattering into pieces.
