Because you are afraid to tell him that you don’t belong here?

"Sweetheart, do you really think. I won't protect myself and leave you in an open room" said Hyun Jin with a smirk.

"What is it?" asked Min Tae but old man replied.

"Invisible barrier" said the old man from behind.

"See you later, love" said Hyun Jin with a smile and left.

"I won't miss next time" screamed Min Tae from behind and all she heard was his laughing sound.

'What is up with Hyun Jin? He took her here in the room with me. She is merely human. But she knew that he is a wizard. He wanted to protect her that's why he kept here. Cause this must be the safest place except for his own room. He was acting strange. He did not act this way, when someone insult his brother. He took someone life for the first time when someone insulted his brother. I saw that with my own eyes. But here he was a bit angry but playful with her. What is it between these two? Does Hyun Jin like her?' thought the old man when the two were busy fighting.
