In order to have Yu Qiao stop bothering with her, especially as his girlfriend is also making her life at university miserable, it is best to just stick with her plan of creating a pretend boyfriend.
When it's all settled, Mo Lihua believes that Zang Fei will leave her alone. The woman's tricks are getting even prettier, and it is just not funny anymore. It's childish and she does not want to deal with it anymore.
Mo Lihua shows' respect' to Yu Qiao's girlfriend, even though most of the time, she wishes that she could kill the woman in her sleep.
'Yeah, she knows my dirty little secret as well,' Mo Lihua smirked in annoyance. It was a big deal before, but now, she does not think so.
If her plan works and Yu Qiao 'miraculously' learns about her 'dirty little secret' of loving him more than a brother, then she can just pretend that it is not the case anymore.
