My Dear Angel [Love You My Guardian]

She was a kind-hearted girl with a cheerful appearance that can even melt a stone. Her life never went easy on her, she was always ignored by people, yet she was nice to them. One day, she was stabbed by a mischievous old lady who was there to enquire about her ill son. As soon as she found that her son was dead, she just pointed her knife towards this innocent girl and killed her cold-bloodedly. This time, she is given a new life where she’s the one responsible for changing everyone’s fate.
