The Gaze of the Human Skin Guesthouse

I checked into a standalone guesthouse deep in the mountains. The owner stayed completely silent the entire time, never spoke a word, only bowed, handed me items, and saw me off. The room was eerily clean, and the walls were covered with exquisite human figure oil paintings. Every person in the paintings stared dead at the direction of the bed. I woke up late at night and found that all the people in the oil paintings had disappeared entirely. After dawn, I never managed to walk out of this guesthouse again. Please deduce: the complete truth, the owner's identity, the reason the people in the paintings disappeared, and my final ending.
