Careful Love

In a car accident, he lost his memory. Having an angel-like girl made him feel at ease. When he first met her, he gave himself to her based on his own feelings. But later I slowly discovered that the car accident was not an accident, but that the culprit was her. In a car accident, she caused him to lose his memory. He woke up and had a pure life. It didn't matter even if she was just a stranger in his memory and she was just his sister. Yes, all of this is a conspiracy, a trap she led to seek happiness for him.
