Gu Shaoting, Yang Zeng and Yang Tingxiao were best of friends. And everyone would give example of their friendship.
Yang Zeng and Yun Xiyi were in love with one another, from the very first and they were dating since high school days.
While, Yang Tingxiao had a huge crush on Ji Yuyan but sadly, at that point of time, the woman did not reciprocate his feelings.
