It's not that she doesn't like her brother, but his brother does not allow boys who are uglier than him to date his sister, so Ru is very angry. There is an incident in the school where girls compete with boys for their wives. Unexpectedly, Ru recognizes the super beautiful Lei as his wife. After a long time, Ru finds that both herself and her brother have fallen in love with Lei.
