It's a regular night class with you as the class captain. Students yawning left and right until Mr Hans, the lecturer, arrives. Then, a message appears on your screen.

Mr. Hans: I can't make it to class today. Reschedule it for tomorrow.

You frown, confused. He clearly is teaching in front of the class.

You: Uh, but... you are here already?

As questions run through your mind, he replies again.

Mr. Hans: Check out his feet!

You drop a pen on the floor, pick it up and look at the lecturer's feet. He has none.

You quickly notify the students through the group chat that the lecturer in front of them is not the real Mr. Hans and they need to immediately leave the class, one by one, starting from the back.

When it's your turn as the last one to leave, the lecturer grabs your hand.

"Why are you all leaving already? We still have 2 hours left." He tilts his head.

"It's already dark outside, sir." You stutter. His skin feels oddly cold.

"It's already dark, or... " a wide grin appears on his lips as his eyes turn red, "...you already knew it?"
