An antisocial personality couldn't be dealt with directly; you had to win them over by flattering them.

Rayne liked Brogan, so I would deal with her by taking advantage of Brogan.

"I have a way to make Brogan marry you. Do you believe me?" I whispered in her ear.

Of course, she didn't believe me because I had previously been very annoyed by her pestering Brogan. But now, Brogan was too dangerous for me.

"I don't believe you, and I don't think you're that kind-hearted. You've always looked down upon me since childhood!"

I gave a sly smile, observing my dear sister.

"You're my sister. If you're happy, I'll be happy too. I don't like Brogan. A forced marriage won't get a happy ending. Since you like Brogan, of course, I'll give him to you."
