I Picked Up a Yandere Girl by the Roadside

Coming home late after working overtime, I found a drenched girl by the roadside in the pouring rain. She looked so pitiful and had nowhere to go, so I kindly took her in. At first, she was sweet and considerate. But gradually, I discovered her pathological attachment to me: she locked every door and window, installed a tracker on my phone, and drove every woman in my life away. Then one day, she held up a bloodstained pair of scissors and gave me a sweet yet twisted smile. “Big brother, now you’ll belong to me forever.”
