You Were the One Who Said You Loved Me First, Sister

[A fake-sweet, secretly twisted older sister 1 x a soft, dumpling-like younger sister 0, sometimes spoiled and sometimes oblivious]

[For a particular kink | Non-blood-related sisters | The balance of power reverses after being reborn | Younger sister takes the initiative more often]

In many people's eyes, Jian Nina is a genuine heiress to a wealthy family.

Her older sister, Jian Youqi, is merely an adopted daughter in name. She was never even registered as part of the family, and is no more than a watchdog living under the Jian family's roof.

But Jian Youqi dotes on her younger sister. Whatever Nina wants, Youqi puts it right in front of her.

Still, what Jian Nina wants most is to escape from her sister.

Jian Youqi is as gentle as water around other people, but controls Nina at every turn. Whether it was her friendships, her education, or even becoming an entertainer, Nina only got her way after crying, throwing a fit, and threatening to hang herself.

How could she not want to leave her?

On the day her girlfriend proposed to her, Jian Nina received a message from a friend:

Jian Youqi was dead.

Her sister and her girlfriend had been taken to the same hospital on the same day, after the same accident.

Only then did Jian Nina learn that her girlfriend had already been in a relationship with someone else and had only coveted the wealth behind Nina.

Even after being exposed, she refused to change her ways and insisted on proposing to Jian Nina.

After the funeral, Jian Nina listened over and over to the recording of their confrontation that day.

Her most hated sister had said, "No one loves Nina more than I do."

*

Jian Nina was reborn at seventeen.

Back then, Jian Youqi had just returned from studying abroad, and Nina was still living in the villa on the old estate. Fate had not yet driven them apart.

After all, it was because of Jian Youqi that Nina had come into this world.

It was because of what her mother had said: "I was never meant to have children, but Youqi was destined to have a little sister, and that's how we got our Nina."

So it was all Jian Youqi's fault. She had destroyed Nina's dreams for the future.

That meant Youqi had to stay by her side far into the future.

*

Jian Youqi has a secret.

She loves her adorable little sister, but her sister hates her most of all.

Lately, though, her sister has been acting a little strange.

She no longer goes to bars or uses homework as an excuse to go dancing. Instead, she sticks close to Jian Youqi, looking at her with hopeful, timid eyes.

She even stops calling her by her full name and starts calling her "Sis" in a cloying, affectionate voice.

Jian Youqi: "Are you short on money lately?"

Jian Nina: "Do I look like I'm short on money?"

Jian Youqi: "Yes."

Jian Nina: ...

I still hate her!
