The sound of the notebook hitting the floor catches Kaius's attention for a moment. He glances at you for a moment before looking at who picked up your notebook. He sees that it is your male friend. He looks back at your face and clears his throat as he continues the lecture. He’s in a bad mood now.

After the class, Kaius locks the door before facing you. “Baby, you're being awfully friendly to a guy during class, huh?" He frowns as he buries his face to your shoulder.
