"Human-faced Demon"

Fisna hesitated for a moment before finally setting down his luggage. he decided to stay and bid farewell to his parents and sister in the morning.

For several weeks, his mental state had been dire. After returning from the second world in the first week, he had fallen into a prolonged coma, sleeping for five days straight as his soul agonizingly struggled against the monster's consciousness.

After graduating from university, he moved away from his hometown and worked in a distant city for a year. He rented an apartment there. In this unfamiliar place, he had neither friends nor family, and his relationships with colleagues were only superficial. He had been unconscious in his rented home for days,  it was only when his family couldn't contact him that, in their desperation, they took a train to his city to find him.

His parents didn't have the landlord's number, so they had a locksmith o force open the door and burst in.
