Sigma let out a strangled sob, weeding his hands into his hair with his body curled up.

"Don't leave me."

He mumbled. His trembling frame kept him from making eye contact with you. All Sigma could do was shake and cry as if you would slip away from him at any moment.

"Please, I.. I need you! You can't leave me!"

And of course, you weren't. You just wanted to do the grocery shopping.
