When I first moved into Alex’s home, everything seemed ideal. Though the house was old, it radiated charm. Sunlight streamed through its tall windows, and every creak in the wooden floor felt like part of its character. I believed I was starting a new and promising chapter of my life. But I had no idea just how strange that chapter would become.

The first thing that stood out was Alex’s German Shepherd, Max. Though he was a large, intimidating dog, he was gentle and affectionate toward me. He’d follow me from room to room and often lay by my side while I worked. I assumed we’d bonded. But there was one place in the house Max clearly didn’t trust—the basement.

One afternoon, while I was unpacking in the hallway, I noticed the basement door was ajar. Curious, I thought I’d take a look and maybe start organizing things down there. But as I approached, Max blocked my path. He growled deeply, baring his teeth. It was completely out of character. His growls were low and threatening, his ears pinned back. Surprised, I backed off, chalking it up to a weird mood.

Later, I tried to go near the door again. Max’s reaction was even more intense. He wouldn’t let me get close, and I was baffled. I asked Alex about it, and he brushed it off with a laugh, saying Max just had a strange dislike for the basement. According to him, it was just old storage—nothing important. Still, something about his response felt… off. Dismissive, even forced.

That sense of unease grew stronger. I couldn’t stop wondering what was really down there. So, the next day, while Alex was at work, I waited until I was sure he was gone. I grabbed the spare key and distracted Max with a treat before sneaking downstairs.

The basement was cold and musty, thick with the scent of mold. A single dim bulb buzzed and flickered overhead, casting uneasy shadows. In the far corner, I spotted an old, dusty chest. It was locked, but I was drawn to it. Then I heard something—soft thudding from inside. My heart started to race.

I opened the chest and found an old photograph of a woman. She looked eerily like me—pale, distant eyes, an air of sadness. Underneath it was a letter addressed to Alex, signed only by someone named “M.” The note read:
“Alex, you promised you would protect her. Now, you’ve failed. I hope you can live with the consequences.”

A chill ran through me. Who was she? And why had Alex hidden this?

Before I could think further, Max began barking upstairs—frantic and loud. The basement light flickered once more, then went out. I snatched the letter and photo and ran back upstairs, locking the door behind me with trembling hands.

When Alex returned, I confronted him. His face went ghostly pale when he saw what I’d found. He finally told me the truth: the woman was Olivia, his former fiancée. She’d died in the house years ago—falling down the basement stairs. Her family blamed him, and he’d always believed her presence lingered. He hadn’t told me because he didn’t want to scare me.

Since that day, I haven’t gone back down there. But at night, I sometimes hear things—faint noises from beneath the floorboards. It’s as if someone—or something—is waiting. Maybe it’s Olivia. Or maybe it’s just my imagination.

Either way, I’ve come to believe some doors are better left unopened—and some secrets are meant to stay buried.
