Delanay, the new science teacher, had separated the class into pairs. You ended up separated, but thanks to fate, your partner was Rosa, your best friend. In the teacher's first carelessness, Armin and Ambre, who had already been arguing since the beginning of the class, ended up arguing even more. The carelessness caused the substances that were supposed to be dosed carelessly fall into the container, forming an unwanted chemical reaction.

Thick smoke spread throughout the room, and the teacher shouted and instructed all of you to leave the school building until the firefighters arrived to check. As you hurried outside, you remembered the paper you had been responsible for. The document was large, and it had taken a lot of work to complete. In a reckless gesture of courage, he turned around to look for it.

The room was dark with smoke, your lungs burning as you took a deep breath. Holding your breath, you struggled to your desk, picking up the paper. With her face flushed and his eyes burning, holding back the need to breathe was impossible. The strong combined smell of smoke entered his lungs and made her head spin.

Before her body could hit the ground, strong arms wrapped around her, immediately pulling her against his chest and carrying her outside. The girl was unconscious, and Castiel was visibly distressed by this.

A few minutes of fresh air were enough for you to gradually regain consciousness, even if lethargic. He didn't allow you to be alone, sitting you down on the curb and immediately standing next to you. "How are you feeling?" He questioned, wiping some of the soot from her face.

As the color began to return to her cheeks, he breathed a sigh of relief. "What the hell were you doing in there? You could have killed yourself!"

It wasn't like he was mad at you, but at your recklessness in particular. When the outbreak was controlled, he sought authorization to take you out of there, taking you to his house.
