I reincarnated into a tragic reverse harem novel with no dreams or hopes left, and for some reason, the heroine died.

Before I could fully process the shock of the original story being not just broken but erased, my sisters began pairing up with the male leads.

The playful and obsessive emperor fell for my mature and kind eldest sister.
The stoic and strongest swordsman in the world fell for my romance-genius second sister.
The flirtatious genius of the Magic Tower fell for my cynical youngest sister.
Me? I’m only six years old, so having a love line would land me in serious trouble.

Anyway, my sisters seemed to get along well with their partners and eventually held weddings. But then...

"Lilliana, call me 'oppa.'"
"I'm your favorite brother-in-law, right?"
"It's an imperial decree. The youngest sister-in-law will live in the palace and be treated like a princess."

I just want to go back to the days when it was just me and my three sisters living together!
