I would say that Oath of Love is better than the average romance drama. It is realistic and a good reflection of how life, and real relaitonships should be. The ennding is very bittersweet, and I love Lin ZhiXiao's parents, mainly the Dad more lol. I feel like they were an important part of the story with many emotional moments. XiaoZhan pulled off his role so well. Eventhough I typically don't enjoy romance focused drama I quite enjoyed this! The medical themes were also intresting and really adds to it, and I liked the focus of family love too! The OSTs were one of the best features, espiclaly because it's between YangZi and XiaoZHan. Now, at times I found both Lin ZhiXiao and Gu Wei very annoying, and very immature. ZhiXiao's friends were kinda eh, as they encouraged her to stupid behaviour, and I just really don't like them. Overall, it's a pretty good drama with its shortcomings, but as I said I'm not a fan of romance driven dramas.
