For me, this is the best drama of 2022 and 2023 hands down. It's not only a love story, there's a whole world around it.
Adult realistic world, with flaws, good and bad, happiness and sorrow.
A story about everyday life, about family, friends, neighbors. The story is very fluent, the relationships have ups and downs but their development is very natural. The main leads, Yang Zi as Lin Zhi Xiao and Xiao Zhan as Gu Wei have amazing on-screen and off-screen chemistry.
One of the important topics of the drama is the age gap between the leads ( 10 years in the drama, 6 in the novel) but in my opinion the perfect word to describe The Oath of Love is communication.
Working in the medical field is not easy and we can see it in the characters of Gu Wei and Gao Xi, similar but with different point of views. An important element is growth and dealing with parents, and in cases with mortal deseases. Age gap, personality difference, insecurities are well highlighted.Being able to compromise and understand each other, is how a couple can develop true love.
It's slow burn romance but not that slow, and the topic of healing is well developed. The relationship between the leads is cute but not cliché. They complete each other, he is mature and has calm personality, but with a gentle and warm heart inside. Lin Zhixiao has a bright and positive energy. They totally match.
Another special thing of the drama are the OSTs.
- "The Oath of Love (余生，请多指教)), opening theme song by Xiao Zhan and Yang Zi shows the perfect combination of their voices
- "Somebody Liking Someone "（一个人喜欢一个人） by Yang Zi is the first ending
- "The Luckiest Fortune" (最幸福的幸运） by Xiao Zhan is the second ending

I really recommend this drama to everyone wants an adult, real and warm love story.
