Picked up a Sickly Girl on the Roadside

When I came home late at night after working overtime, I picked up a soaked girl on the side of the road during a heavy rainstorm. She was pitiful and homeless, so I kindly took her in. At first she was well-behaved and sensible, but gradually, I discovered her morbid attachment to me - locking all doors and windows, installing location on my mobile phone, and driving away all members of the opposite sex around me. Until that day, she held the bloody scissors and showed me a sweet but twisted smile: "Brother, now you will only belong to me forever."
