She is called the original heroine, but she is actually a female cannon fodder. Oh, she can still tell them with the facts that all the changes will only make her more glorious.
World 1: Gentle official lady x arrogant and domineering eldest princess
Shouldn't she fight back when she knew the two were engaged but still got involved?
World 2: The child bride who works as a cow and a horse x the spotless green plum next door
It would be boring for you to pick peaches in the name of your true love after she cheated and provided you with a top pick.
World 3: Gentle and virtuous business woman x ambitious scholar's daughter
If it were another person, she would still be able to live a peaceful life
Intention: As long as you keep a calm mind and move forward hard, all difficulties will be temporary.
