I, Aoto Ichigaya, was hated to death by my stepsister, Shizuku Ichigaya.

The 'big brother-loving stepsister' trope common in romantic comedies was nothing but a fantasy. Every day, my real stepsister would tell me to get lost or drop dead the moment she opened her mouth.

Just as I had grown accustomed to such treatment and was about to give up on our relationship...

A lie I told on a whim

would drastically change our brother-sister relationship.

“...You damn big brother... The hypnosis, it's definitely working, right?”

“O-oh, yeah. It’s working... *mumble, mumble*”

“Then, kiss me.”

“Huh...?”

My stepsister, who constantly tells me to drop dead, is trying to make me fall in love with her using hypnosis while I’m asleep...!

*Hypnosis appears from Chapter 3.
