Summary
Ever since my brother found out I wasn’t his biological sister, he’s been incredibly cold toward me.
I was devastated.
While packing my things to get the hell out, I accidentally stumbled upon his diary.
[I’m screwed. She’s not my biological sister. I can’t control myself anymore.]
[I want to kiss Susu’s… little sister so badly.]
[She can’t even solve such a simple advanced math problem. My heart hurts from frustration; I really want to take a whip to her.]
[She can’t even solve such a simple calculus problem. My heart actually hurts from the frustration. I really want to take a whip to her.]
[The bathroom is so small, yet she insists on squeezing in. Does she want me to ram her until her pupils lose focus?]
[If she calls me “Brother” one more time, I’m sending her to the North Pole to pull weeds.]
I closed the diary.
Quietly, I walked down into the basement.
With trembling hands, I picked up the chains, the candles, and the leather whip.
Brother, you can whip me during the day.
But at night… it’s my turn to whip you.
