Please Become My Sister-in-Law!

"So, what do you think about my brother?"

One day, out of nowhere, a charming princess appeared in the life of Claire, the mistreated protagonist of an unknown author's work. Princess Yuri, without any prior connection, unexpectedly proposed that Claire marry her brother—known as the empire's most eligible bachelor. Overwhelmed by the princess's stubbornness, which not even the emperor could sway, Claire found herself in a contract engagement with the second prince.

"I just want you to play along until Princess Yuri is satisfied. I'll make sure you're compensated accordingly."

As Claire waited for the contract to end, Prince Raymond began to approach her. Why would someone who is only tied to her by a contract...?

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

For Claire, who fears both giving and receiving love, the wave of affection from her potential in-laws has only just begun.
