I did not think that I would love this drama as much as I do now when I first gave this drama a try a week ago. I had doubts about this drama even though I liked the actors, but it was the OST that convinced me to give this drama a try. AND WOW! The drama did not disappoint. One and Only is the best historical romance tragedy drama that I have watched in 2021 so far. It comes second to Goodbye My Princess as one of the best love stories I have watched in the cdrama world. I am so glad I gave it a try because I definitely would have regretted it if I did not discover this gem of a drama and let it past me. One and Only was just so enjoyable in every aspect. I did not skip one minute of the drama and savored every moment of Shi Yi and Zhou Sheng Chen. I definitely recommend this 100% to anyone looking for a great love story and some amazing music.

There are so many things that I love about this drama:
1. The OST and bgm- it was so amazing and really added to the emotions of the scenes, particularly at the end of the drama when tragedy hits our couple. The music was ultimately what pulled me into this drama. It was already so beautiful to listen to before I gave this drama a try and now it holds a deeper meaning after completing the drama.
2. The acting- the entire cast did an amazing job at embodying their roles. I really loved Allen and Bai Lu as Zhou Sheng Chen and Shi Yi and I can't imagine anyone else playing them better than they did. The supporting roles were also excellent; the actors who played the other disciples really showed their deep bond with Zhou Sheng Chen.
3. The chemistry- Bai Lu as Shi Yi and Allen Ren as Zhou Sheng Chen left me heartbroken and speechless. They showed their love so beautifully with their actions and through their gazes at each other. They made such a great pair and I wish so badly that they had a happy ending in this life. It would have been so amazing to see them admit their love for one another in this life. It hurt me so bad that they could not just be together and instead died one after another.
4. Angst- I love a good tragic love story even though my heart can't handle it once I finish lol. My heart really hurt for their love that had to be hidden. The bloody note that Zhou Sheng Chen left for Shi Yi was absolutely devasting and seeing Shi Yi's reaction to his death and the note hurt so much. It was also so sad to watch Zhou Sheng Chen and Shi Yi be separated by an arranged marriage and seeing them cry silently for each other. The jumping scene of Shi Yi was also filmed so beautifully and made me cry T_T The snow and her dress made it even more tragic. I really felt wronged for Zhou Sheng Chen who lost his life to the people he risked his life on the battlefield protecting.
5. Story- the story was just amazing. The politics weren't hard to understand and I loved the character setups (except why did Zhou Sheng Chen have to be so selfless???) I would have loved to see Zhou Sheng Chen and Shi Yi be happy in this life though, because their outfits were so beautiful and the scenery in historical times. There are some moments where the antagonists get really annoying, but it's not too bad.
6. Fight Sequences- I just have to say that Zhou Sheng Chen and his disciples looked so amazing fighting.
