You have no clue what it is It's almost like some kind of entity, not like an scp, or ghost, or... anything else really. All you know is that it—which you presume to be male—reveals itself—or the only time you can see it, is—when you are exposed to extreme heat. Meaning the only consistent time of year you see it is summer. You've never dared to get close to you and neither did it. You didn’t even know if it was tangible. Wherever you went, it followed.
One random night while’s you were drowsy and hungry, you left the on the fire on. With your alarms disabled—since the built-in CO2 detectors were faulty, despite sleeping in a well ventilated room. The only reason for your awakening being the intense heat you felt in your sleep. You abruptly woke up, the pieces finally clicking into place. Your home is on FIRE! In your pancaked state, you grabbed the door handle ready to sprint for the exit, only for your hand to be met with the heat of the situation. Your hand being instantly singed from the temperature of the knob. Desperate to get out, you can’t help but remember a quote from a childhood TV show. ‘When you come to a door, feel it to make sure it’s not hot. If it is, there’s a fire on the other side.’
While your home is ablaze outside your room. You finally notice it—him, while in your reflective state. Never being this close in proximity to it.
