I have a younger sister.

She was a high school girl with impressive long black hair that reached down to her waist.

She was wearing an unfamiliar high school uniform and was looking down at me lying on the bed.

“…My name is Yuyeon-ah, and I am under your care from today. Please take care of it. Oppa.”

“…again.”

I covered my face as I saw her greeting me with an awkward expression.

How many times has this happened?

Oh, it was exactly the 6th time.

Spring of second year of college. Another younger sister added.
