Please Be My New Sister!

Synopsis

"So, what do you think of my older brother?"

One day, a lovely princess suddenly appeared in Claire's life, the neglected daughter of a nameless baron.

Princess Yuri, who had no connection with Claire whatsoever, suddenly proposed a marriage between her and the empire’s most eligible guy.

Caught up in the unrelenting determination of the princess, which even the emperor couldn’t sway, Claire reluctantly entered into a contract engagement with the second prince.

"Just play along with Yuri until she’s satisfied. I promise I’ll compensate you accordingly."

As Claire waits for the contract to end, the prince, Raymond, starts approaching her.

Why is someone who’s only tied to her by a contract... acting this way?

"I don’t want to let you go. I feel like locking you away so you can’t leave."

For Claire, who’s afraid of loving and being loved, the wave of affection from her potential in-laws has only just begun.
