บท 190: Librarian's Mistake

Rainn's jaw tightened at the words that came out of Gremory's mouth.

'She is a fucking Demon after all!'

Although now he knew that both Angels and Demons both had ulterior motives. Rainn thought that between the two Supernaturals, Demon was still the most annoying.

Gremory tilted her head and showed a mischievous smile to Rainn.

"Hmm? What's with your face? Are you mad?" Gremory asked in a playful tone.

Rainn glared at her again. But he knew that there was no point in venting his anger by cursing this Demon right now.

"Hhh..." Rainn took a deep breath. Trying to let out all the anger that is in his chest. "So you're not going to tell me?"

Rainn asked once again. "Hmm... it depends. Do you want to be my slave?" Gremory replied with a smirk.

Rainn sighed again. "You'd better go now."

"Ahahaha! Are you sulking?" Gremory said.

Rainn didn't want to respond to his words anymore. He chose to lie down on the bed and picked up his cell phone.
