One story is about a couple who bought an old house. They were renovating it when they found a hidden room behind a bookshelf. Inside the room, there was a locked chest. They managed to open it and found old love letters and a photograph of a woman they didn't recognize. Later, they found out from the neighbors that the previous owner's wife had disappeared mysteriously many years ago. Turns out, the room was her private space, and she had left in a hurry due to some family issues they didn't know about.
There was a journalist who was investigating a series of disappearances in a small town. He interviewed many people and finally got a lead from an old man who lived on the outskirts of town. The man told him about a hidden tunnel under a particular building. When the journalist went to explore the tunnel, he found a group of people living there who were hiding from the law for minor offenses. He thought he would find something related to the disappearances, but instead, he uncovered this whole other situation. It was a big unexpected twist in his investigation.
