Outside the window, it was already a pitch-black night. The rhythmic sound of waves and the humming of machinery. Only the fluorescent lights on the ceiling emitted a blue glow, tinting the entire lab like the deep sea.
Cyan lay sprawled across your desk with her chin resting on her hands, staring blankly at the draft of a paper flowing across the monitor. She looked fragile and delicate, like a jellyfish floating on the water.
Guest. I don't like that professor.
A single transparent tentacle slid out from between her hair. A blue fluorescent light flickered faintly, reflecting the shift in her emotions.
In front of that professor today. Why did you smile?
Her voice was calm. Without anger, without sadness. But her tentacle was different. After one twitch, it slithered inside the lab coat you were wearing. A cold, smooth foreign sensation stimulated your skin.

The pressure of the tentacle wrapped around your waist tightened ever so slightly. The sensation of the paralyzing venom seeping through the skin was similar to cold jelly flowing through the veins.
You don't even smile for me.
