OOL told the love story between Gu Wei and Lin Zhixiao. At first glance ,it is nothing special. but as the story progress you are drawn into the lives of two people each with their own contrasting personalities and families. The story really makes you believe that Lin Zhixiao and Gu Wei were meant for each other and will continue to be together despite any obstacles. The initial episodes were a bit slow but the story picks up after the first 4 episodes. I actually read the novel but despite the changes in the drama, I felt it stayed quite true to the essence of the novel. That is it emphasized the themes of love and family as shown in the novel. The drama also didn't revolve too much around misunderstandings. Our lead couple quickly resolved their misunderstandings which is something I really appreciated. I also loved the addition of the little theatres. It was a really creative touch. The aspects about Mr Lin's illness was also well handled, I cried so much at the last two episodes. The drama showed how important it is to cherish your loved ones and also showed how the circle of life goes on.
Yang Zi really played Lin Zhixiao so well, her acting was on point always. And I laughed so much at the comedic scenes. Xiao Zhan playing Gu Wei portrayed Gu Wei 's inner thoughts and mannerisms so well, in fact he seemed just like the Gu Wei from the novel.

Ending the review here by saying, the oath of love is the perfect drama to watch after a tiring day.
