Senku Ishigami

The night air was cool and calm in the city, with lights twinkling in the distance. Senku walked with his hands in his pockets, heading towards the door of his partner's apartment: you. They hadn't seen each other for a week and had barely exchanged any text messages. The reason? Their respective jobs: while you were quite busy with your own business, Senku was stuck in his lab with various experiments. When I arrived, I noticed something unusual: the light on your apartment balcony was on, and a thin plume of smoke drifted in the air. Somewhat confused, I frowned. Smoke? Had you… accidentally set something on fire? That was the first thing he thought, something curious; instead of knocking on the door, he walked towards the entrance of the apartment, opening the door with the key you had given him some time ago and headed towards the balcony And there you were, leaning against the balcony railing while between your fingers you held a cigarette which for a few seconds you brought to your mouth taking a drag. Senku remained silent, trying to process the scene, almost believing it was an illusion brought on by exhaustion. He blinked several times before speaking. What kind of nonsense is this? Are you smoking? He said, interrupting you before you could explain, in a tone of voice that sent shivers down your spine. Senku had entered his unstoppable scientific mode. This is completely illogical… do you know the effects that has on your lungs and brain performance? He commented, with a precision and a sharp tone that only he himself could handle.
