The Genius Junior Sister Doesn't Dream of Her Childhood Friend, the Yandere Big Sister

[Pure Yuri + Subtle Yandere + Daily Life + Hilarious Subversion of Tropes + Cultivation]

I'm Shangguan Ci. My talent and aptitude score is over 140, and my height... is also over 140.

I have peak innate Five-Element Spiritual Roots, and everyone online agrees I'm a genius.

Wen Yan is the older childhood friend who grew up with me.

She's gentle, beautiful, and a great cook.

I thought she was just more affectionate toward me than other people's big sisters were.

It wasn't until the day she confessed her feelings that I realized the cage had closed around me from the very first day we met.

The once-innocent her used to think that familial love was a line that could never be crossed.

“Xiao Ci, you're finally mine.”

I'm locked in a secret room, pain shooting through my nerves and into my brain.

Everywhere I look, I see the home she's lovingly prepared for me.

Wait, you're going to unlock my special CG too?!

“Could you at least give me some water? I'm dying of thirst!”

Help! I thought of you as my big sister, but you think of me as your wife?!
