"Our Blooming Youth" is a tough drama to review. On one hand, it is one of the few political power-based sageuks that had a story that kept me interested, but the story and romance, and mysteries all happen at a snail's pace. Thankfully the cast is great, the leads are charming and likable, and there are entertaining comedic moments, otherwise, this drama would have been extremely boring for way too many episodes. The plot often took too long to explain the obvious, and the corruption plot was very confusing to me until the final episodes because they waited so long to show backstories. Still, I think the slow pace also gave us time to get to know all of the characters better and I really did grow to care about many of the characters.

The show stars Park Hyung Sik as the charming prince and he is perfectly cast. He is matched with Jeon So Nee as Jae Yi who meets him in disguise in order to clear her name. From the beginning, I loved that they were both clever and brave fighters, which made their chemistry seem natural and evenly matched. There were definitely times when her actions frustrated me, and also times I wished their relationship would progress more, but they did stay true to the tragic mystery and corruption plot instead of just taking a full romance detour, which I can appreciate too. The rest of the main characters are just as charming.
Pyo Ye Jin and Lee Tae Sun had their own cute chemistry as master and apprentice. Yoon Jong Seok played loyal and stoic well, and Heo Won Seo was super cute and one of my favorites in this drama.

Another favorite of mine was Jung Woong In who just plays evil so flawlessly. Just his creepy smile alone is epic.

There are no weak links in this entire cast except for maybe Im Han Bin as the younger prince, but I'm going to blame that on his awful wigs, not his performance. You know the cast is good when you genuinely care about what will happen to minor characters as much as you care about the leads. I also appreciated that the story gave these characters fuller storylines that helped create well-rounded characters not just cliches you expect to see. I empathized with some villains as much as I empathized with the heroes. Not a single character felt like filler. That's one thing the writers did very well.

What I wish the writers did better was make a less confusing mystery plot. It was only in the last 2 episodes that I was finally able to understand what had happened in the 18 episodes before. This plot had poisonings, massacres, ghost stories, revenge, gaslighting, betrayals, and a rag-tag mystery-solving squad but so many scenes went over my head as I struggled to make sense of it all. I think that's the main thing that stopped me from loving this drama even if it all made sense by the end.

Would I watch this again? Maybe. It is so slow-paced, but maybe binging it would help. I think knowing the full story may help me pick up on things I missed if I watched for a 2nd time. There are also cute and funny scenes but I'm not convinced there were enough to make me want to watch this all again. Knowing what will happen also dulls a lot of the initial excitement.

Overall, this is a good historical drama but you have to really be in the mood for a slow-to-reveal mystery. There is romance, it's one of the main plots of the story, but don't expect too many actual romantic moments, which may disappoint romance fans. If you are a Park Hyung Sik fan he will not disappoint. Royalty looks good on him. If you watched enough sageuks a lot of the plot will feel familiar but the overall story is original enough to stand on its own. I am curious to know what the CDrama version is like, but I'm not sure I'm curious enough to actually watch it. I would recommend "Our Blooming Youth", even if I still don't understand the title, and just tell folks to grab plenty of popcorn for the slow pace and trust all roads to lead somewhere satisfying eventually. I also loved the themes of trust, loyalty, and true friendship! Like an act of well-planned revenge, give this story time to build to make the best impact. Dragging or not this drama definitely made me glad I watched by the end.
