She screamed with her scared then caught her senses back feeling confused but also concerned
"AAHHHHH!..What happened!? What's Wrong!?"
"Nnn...ah-owwww..."
She rubs the back of her neck, wincing. I should mention that Rein felt a dark aura from the mark
"..What is on the back of your neck."
"H-hm...?"
"Look at me and tell me the truth. What is on the back of your neck?"
"I-it's...nothing."
She's not making direct eye contact with Rein
"I said the truth Delta, what is on the back of your neck."
After she let go of her waist and moved away backing away from her in the bed and she got up and just walked over to the staircase and started walking down stairs
"...R-Rein, wait!"
She runs downstairs after Rein
