Protagonist A has a selfish mother, supporting character B has a philandering father, cannon fodder C has a snake-hearted brother, passerby D has a sister who is different from what she looks like, and villain E has a hypocritical brother. Some of the latter promoted the development of the story, some caused the former to completely change, and some completely hindered it... But one day, they are still them, they are still them, but their 'cores' have all changed...
Intention: Work hard and strive for a bright and beautiful future.
