My Childhood Friend Dotes on Me, but She's a Yandere

Urban slice of life + one heroine + older woman + older sister and younger brother + yandere + scheming heroine + strong woman, weaker man

At his high school graduation dinner, Chen Xi was rejected by the campus beauty he'd secretly loved.

Then the older girl next door, his childhood crush and childhood friend, appeared out of nowhere like a dream.

Lin Wanqiu: "You little brat, hurry up and call me Big Sis."

She had left without a trace seven years ago, and seven years later she appeared without warning.

As time went by, Chen Xi discovered that Lin Wanqiu was a doting big sister who spoiled him rotten!

"Little brothers are meant to be spoiled."

"Xiao Xi, you need to understand that only your big sister treats you well. Everyone else out there is bad…"

"Depend on me more. Just look at me. From now on, you'll only need me…"

Seeing how close the two of them were, the campus beauty who had rejected him cried with regret.

Chen Xi was absolutely thrilled.

"Isn't this great? It's wonderful! I'll only ever love Big Sis!"

But then, one day…

Lin Wanqiu looked at Chen Xi, his arms and legs bound, and smiled with a crazed, sick delight.

"Xiao Xi, didn't you say you'd love Big Sis forever?

"Now, what are you going to call me?"
