ONE AND ONLY (2021) was a great Cdrama, especially if you like historical period and costume dramas. I admit, I had a difficult time getting into this one at first. I had a few false starts and dropped it several times before going back to it, due to the seemingly predictable and generic romance.
Once I finally got going however, I discovered it was a really good show, and quite short in terms of average Cdrama length (24 eps instead of 60-80+ eps). I noticed it used flashback scenes more than other dramas in order to condense the storyline. While I do enjoy the longer series (as they create a depth and deeper emotional bonds), but this was a nice change of pace.
" A young man determined to become a general takes a mute, ill-fated princess as his disciple, forming a forbidden bond amid palace power struggles."
The actors were all very good in their roles, and the characters were all very likeable as well. The story was a bit slow starting, focusing on the blooming romance aspect rather than on the rest of the story, but gradually became more interesting and compelling, especially as villains and other main characters stepped into play. I really enjoyed the music as well, it was very fitting.
Overall, ONE AND ONLY was a great watch. I recommend if you like historical romantic Cdramas. Must warn, it is tragic and emotional.
