[Wealthy families + biological siblings + romance + everyone dotes on her + strong female lead + lighthearted]
On the day Yun Can was abandoned for the third time, he'd already resigned himself to picking up bottles for the rest of his life. Then a beautiful older girl appeared out of nowhere.
Yun Man was beautiful, kindhearted, and a real go-getter. Without a second thought, she whisked him home.
“Don't think you can buy me off.”
“Sure. Dinner's on the table. Which new pajamas do you like?”
“...That's not what I meant!”
From then on, Yun Can was forced to endure the “hardships” of being doted on by his big sister in every way: being made to eat breakfast, having her watch him try on new clothes, getting taken to amusement parks...
He swore he wouldn't cave, until he became the most envied kid at school.
“Your family's estate is huge!”
“Your sister is so beautiful!”
“Is your sister looking for another little brother? One who's been to college?”
Yun Can finally snapped. He pulled her behind him, his face bright red, and declared his claim:
“Everybody back off! Back off! Back off! She's my sister. Don't you have sisters of your own?!”
