A bomb

Shera was no longer looking at Leo. Her gaze was drawn to her phone which was on the coffee table. Leo noticed this and followed her line of sight. A beeping alarm resounded just as he saw the notification on her phone.

"You had a countdown timer?" Leo's eyebrows furrowed in confusion. "What is that for?"

Shera tore her gaze from her phone and nonchalantly responded. "A bomb."

"A… what? Don't go around joking about such things." Leo glared at her.

"What if I do?" She closed the distance between them. "What will you do? Stare me to death?"

Leo had a feeling that she had done something covertly. It may not have been an actual bomb, but it had to be something - or else she wouldn't be joking around and taunting him about it. He aggressively grabbed her chin with his right hand, looking right into her eyes. "What did you do? Shera Black! I'm asking you."
