Because the heroine's parents were so loving, they sent the heroine to the human world, where she met her childhood sweethearts. Unexpectedly, the childhood sweethearts in the devil world also found their way to the human world, so the three of them became childhood sweethearts. Their parents were so loving that they were so loving that they forgot about them. There was also the heroine, and they gave her two brothers and a younger brother. I advise you not to believe the author's words.
