Karina slowly grasped the oxygen tube attached to Fanny's nose and pulled it, causing her to immediately convulse.
"Wow... So you really only live because of that device," she said, not smiling and folding her arms, watching Fanny convulse with her chest heaving and her eyes slowly widening. "I thought you would die instantly, but it seems you have to suffer first."
"Hey!"
A man's voice behind her startled her, causing Karina to step back and see that the man was Tristan, who quickly reattached the oxygen tube to Fanny's nose.
Karina was surprised, her lips seemingly unable to move, watching Fanny readapt to the oxygen while Tristan stared at her sharply.
"You're truly a devil!" Tristan exclaimed with fiery eyes, then pulled Karina to leave the room.
"Tristan..."
"You truly embarrassed me!"
"Tristan, let go of me!"
Tristan immediately released his grip on Karina when they reached the door, then glared at her.
