"Mingi get back!"
Seongwha yelled before throwing holy water at who he thought was an intruder.
"Ow! What the fuck was that for?!"
The demon felt the water burn against his skin. He looked at Mingi.
"Why summon me if you're just gonna have friends throw holy water on me! That stuff burns you know!"
"I didn't mean to summon you and you know that! It was an accident!"
Mingi felt someone hit the back of his head.
"You don't just accidentally summon a demon. You can't just trip and fall into a summoning.
Hongjoong exclaimed.
"But you can trip and fall into a human sacrifice, I would know."
"Now is not the time for jokes Woo!"
