I thought One & Only, despite it is a fact known since 1st episode that they are tragic lovers, they truly have fantastic relationship throughout. They understand each other like what soulmates would, no misunderstandings, and they found calm and tranquility with each other which was beautifully portrayed throughout the drama. When I watched it, I really like this part. Its like 'you & me' against the world, until, the world is really against them which is like the last 4 episodes. I could never rewatch this. I expect the heartbreak, but didnt expect it will escalated to that extend.

I love how the heavy atmosphere can be noticed since in the earlier episodes with the way the Director shot everything and doing the lighting that matched the tone and seriousness of the whole topic. And these heavy feelings will keep following you despite the drama are filled with really fantastic relationships between all the characters at the Royal Mansion. The flashback scenes are also done marvelously to portray the happiness and regrets and why those relationships are fantastic since it was backed up with strong history of kindness and thoughtfulness of the ML -- thats what his students remembers him and why he is so treasured by everyone.

The pining and yearning and the silent of it all really makes this drama a really heavy watch. The fact that both leads barely do anything even a simple thing as holding hands yet you can still feel the electrifying chemistry and agony are just testament on how great both of them at conveying their characters. I will never recover from this one. My heart hurts just when I think about their ill-fated romance.

I love this drama to pieces since the acting in it is really amazing, both of them at the top of their game in this show. Ren Jialun with his micro expressions that kind of pierce through your heart and Bailu's with her amazing portrayal of the mute character and her crying scenes are probably one of the best I've seen in Cdramas and we do know Cdramas has really a lot of amazing crying scenes.

Zhousheng Chen is mesmerising to watch. You can actually understand what he's thinking. You can follow his dilemmas and engage with his feelings, even though you can barely see any expression on his face. Ren Jialun is really good at this. He is supposed to be this cold general but despite he is not very expressive, you can understand and feel the torture his character is feeling. All these are achieved from small change of expressions, how the eyes move, or how his lips will trembles. All these are very small and micro but very effective at conveying emotions. There is one scene where people are questioning his manliness for having no attraction towards women (due to his vow) and while on the outside you can see he is trying to be unbothered, you can feel how his inside is crumbles due to that comments -- and the way he acted coupled with the way Director shot this particular scenes clearly demonstrated that. It was really excellent.

The yearning and unspoken love are the main theme of their love story. The way they communicate to each other using their eyes speaks volume than words could ever say. The big sacrifices and grand silent gesture only happen in the later episodes. And those scenes are so impactful, heart wrenching and the reasons why the drama are so unforgettable to many.

I think the biggest attraction of the series for me is that the leads has amazing and fantastic relationship throughout the drama -- soulmate kind of relationship and understanding of each other which pretty much unmatched -- since they dont have to tell each other anything but they know each other deep into the souls. It is such a nice thing to watch how that understanding develop into something unbreakable and deep. And the drama as a whole is poetically beautiful that some of the simple scenes have so much meanings and poignant when you understand the underlying message of it. It is really a beautiful drama through and through in my book. And the cinematography is A++ without a doubt.
