When he hears that, he doesn't know how to react. Did this idiot girl forget that he's a vampire?
Then, he notices Se-Yong's scornful eyes. Oh! She has nine demon brothers. Her mother is a demonic goddess. It's not strange that she's not afraid of him.
Hmm! She's immortal. He can't kill her for being daring. He needs her until Fu Mian's curse is lifted.
A flurry of thoughts rushes thoughts his mind before he lets out a sigh and makes some distance between the daring girl who isn't hiding the admiration in her eyes and himself who certainly has no interest in a little girl.
The circle is gone. Se-Yong grabs his sister's arm and pulls her away from the vampire king. "Na-Mi, did you hear what you promised him?"
"What?" Na-Mi frowns at him. "I said what we agreed upon."
