Something's Wrong with My Brother!!!

Flirtatious acting pro x tsundere who can’t help falling for her

Fake step-siblings with a brother-and-sister bond, happy ending~

Yun Qingqing grew up in an orphanage and lived by one rule: resources are limited, so grab them first or get left with nothing.

After her sixteenth birthday, a couple came to see her and asked her to save their son, Yun Yiheng, who was practically “dying.”

The solution was simple: pretend to be his “younger sister.”

A mansion to live in, a good school to attend, and pocket money to count.

Only one KPI: be a good little sister.

Yun Qingqing: What a deal!

When a free pie falls from the sky, you might as well eat it. Worst case, she could wipe her mouth and run once she was full.

To make herself feel better about it, she decided to be the best little sister in the world: “Are you cold, Big Brother? Want some water? Tired from playing basketball? Big Brother, want me to massage your legs?”

Yun Yiheng: ?

He gave the fluttering butterfly a cool look. “Tch. More like a moth...”

The more annoyed he got, the more he got used to her.

The more he snapped at her, the more he fell for her.

Until...

He found a paternity test.

Meanwhile, Big Butterfly Yun flew home and smiled as she sidled up to her brother, only for him to pin her to the sofa.

His voice was low and husky. “I don’t want to be your brother anymore, ■■■■■.”

Yun Qingqing’s smile froze.

From then on, she amended her survival rule: stay far away from Big Brother!!!

The author thoughtfully included a shorter version of the blurb:

At first: “Big Brother, are you thirsty?”

Later: “Little Sister, why are you running?”

If you like it, give that lucky little hand of yours a tap and add it to your favorites~
