Huo Shaoheng is always jealous when it comes to Nianzi and Prof He Zhichu's intimacy . Most especially when Huo Shaoheng is in the dark of what is happening.
Nianzhi should be more self aware. She knows Prof He's feelings yet she Carrie's on with him like a spoiled child. Also look how jealous she is of all the females around Huo Shao.
