Unfortunately, she married her younger brother's father. What's even more unfortunate is that the person she hates the most is her destined lover...
That year she ran away from home after learning about her life experience and met her husband; that year his business failed but he found love again; that year he returned to that place to look for a promise, but accidentally fell in love.
In fact, the story is very simple, a story between a woman and two men, but the relationship is very complicated, because one is the father of the younger brother, and the other is an older brother who is not related by blood.
The novel touches on ethics, so don't misunderstand it as pornographic.
As for why there are messy relationships, please read the novel.
