Han Ruochen initially didn't want to expose the truth about Meng Yunhan giving their family's savings to someone else, and that too to her old lover. Of course, Han Ruochen was not stupid enough to expose the matter of Yun Xinye right away. She didn't have enough evidence to prove that Meng Yunhan was having an affair, and if she were to expose the truth right now, she would only give Meng Yunhan an opportunity to turn the situation around.
But Meng Yunhan kept threatening her freedom; Han Ruochen could not help it and revealed Meng Yunhan's little secret. She wanted to see what Meng Yunhan was going to do once her father found out that she had stolen all of their savings.
It was also time for her to let her father know what the situation at home was; she didn't want her father to continue working hard only to fill the hole that her mother had created foolishly.
