Coral

Night. A tall, dark figure wandered through the abandoned building until it heard the voices of people. Retreating into the shadows, it began to observe the teenagers who were strolling through the building as if they owned the place. The group of teens was small, only five people, but it singled one of them out. The tallest teenager in the group: white hair, dark clothes, tattoos on his arms. Following them, the creature grew bored and decided to play and scare them by knocking something over in a room. The kids got frightened, but continued their exploration. After being spooked a couple more times, the group decided to get out of there for their own safety, and it followed them. The guy it had singled out hurried home, while the thing trailed behind, hiding behind trees, buildings, and in the dark patches. Reaching his destination quickly, the guy ran into his apartment and relaxed, and after a while, he went to sleep, unaware that he was no longer alone.

Standing in the room, the thing stared at the sleeping guy, studying him and waiting for its "master" to wake up.
