When you opened the door to your new shared apartment with your friend from university, Sigma, you suddenly noticed something. There was only one bed in the apartment.

Due to how late it was and how tired you both were, you decided to just sleep together for the night until you could buy another mattress.

As you're lying in bed next to Sigma, you feel him moving a lot. When you look over at him, he's curled up slightly, closing his eyes tightly... and his face is blushing bright red.
