To some this might be a generic drama, to others perhaps a bit rushed and flawed in concept. However... 'Let Me Be Your Knight' is much more than your typical drama if you take a moment to see between the lines.

It may not be perceptible on the first time watching, but the hints are there in every single episode.

This is what we can call a "cycle of healing" kind of drama.
Where the true essence resides in the characters as a group.
And into their own personal problems and self-healing that may affect those around them.

The thing is they did it with a K-pop concept and with a band in the center grounds along with the pros and cons.
LUNA is the core of the whole show. Their personal journey as they all struggle with personal feelings and problems while trying not to fall apart. The five of them are the main characters here, and the FL joins the journey with her "baggage" too.

Hilarious how she being a chaotic mess, can be the solution to Tae In's problems and become his muse in times of need. Sometimes, we find the simplest solution within the problem. He only needed to find another model to get inspired, to set different goals and find where his own strength relies on. Not only in Yoon Joo but also realize how isolated he made himself to be when it came down to his band member's. The bigger the house, the wider the distance. It was a good indirect example of how in a bigger dorm the members grew a part within the years ever since their debut. It's a reality portrayed here.

This drama is not solely meant to be a romantic comedy of sorts, although it's implied in the tags.
Or a drama about a thriving band in the music field trying to cope down with their unstable leader at first.
It's about the growth and maturity they face by facing themselves and their own ordeals to finally find the right path.

Sometimes, going back to our roots is the best outtake we can find. 'Less is more' as people tend to say.
It takes 12 episodes here to realize that. It takes a few scandals, several setbacks, blatant lies and some hidden truths.
Overall, within the characters we find a few valuable lessons to behold upon if we set our eyes into the big picture here.

The plot doesn't always have to be straight to the point, sometimes the hints are insidious but are there.
We just have to see beyond and unveil the theories or be able to gather the perception of what it's revealed.

Tae-In's sleepwalking for example is not only about the great amount of stress he has to achieve perfection, but also the sheer pressure he has faced ever since his childhood, only to appease to his classical music genius of a father who tried to mold his son based on his personal taste which resulted into a trauma that led to how the drama starts in the first place. Cliché, right?

Nothing too out of the ordinary. This drama isn't about plot twists or epic cliffhangers. It's all out in the open here. It's the typical clichés packed into a somewhat cool concept.

Which now leads us to the band - LUNA - set into the world of K-pop industry, this drama present us the view of idols, (more precisely a band instead of a group, which is awesome given the numerous K-pop group dramas lately, one with a band playing musical instruments is a breath of fresh air), the concerts and vibes of the past we miss, all the packed schedules, comebacks, albums, lightsticks, fans, venues, talk-shows or radios and even live streams. We see it all, not forgetting to add in fans, discussing their bias and also the troublesome sasaengs (dangerous stalker "fans").

They manage to create the perfect band with mostly idols from quite a few famous K-pop groups:
Lee Jun Young from U-KISS as Yoon Tae In
JR from NU'EST as Lee Shin
Yoon Ji Sung former WannaOne as Kim Yoo Chan
Kim Dong Hyun from AB6IX as Woo Ga On
And although Jang Dong Joo as Seo Woo Yeon is mostly an actor he could be a rising idol too.

Jung In Sun did a good job here playing twin sister roles.

I hope that I am not the only one wanting that LUNA would be real enough to release something in RL too.
The songs are catchy, although the lyrics seem silly some have subliminal messages within the absurd linked words.
We find ourselves singing along, or even tapping our feet to it. Infatuated with the way all 5 members sing and play.
By each and every episode, we keep rooting for LUNA to thrive and overcome their endless troubles.

I wanted more of LUNA songs, shows, whatever, but they focused more on their problems rather than the music. And although it's frustrating and seems to drag until the final episode at one point with the ML and FL "dramarama", it's by the final episode that we realize why it was so. Because to solve things they needed to be reminded of the past and the start so they could rise up once again. The drama also tackles down several known problems from love scandals, bullying accusations, failures, secret relationships, demanding and greedy parents, scams, controlling CEOs, and many more. Despite the setting and the way they did it, we can't deny these happen on a daily basis in RL too. It's a slice of life packed in 12 episodes, bound to be rushed.

But it's in the small details that we're able to find the creativity placed into the scenes.
Like their title track and comeback song being called 'Beautiful Breakup' to the lyrics and meaning, that leads us to one of the scenes in the final episodes where the album is plain sight. It's a realization and a fear, but also a wakeup call to them all.

Overall. I actually enjoyed the acting, the cinematography and music here.
'Beautiful Breakup', 'Love Paranoia' and 'Let Me Be Your Knight' become a fan favorite of mine.
The reason for such a high score is by all that and because of the whole spectrum of problems portrayed.
Not every drama is in fact flawed or perfect, some even fall down in between, while other's are a few rare gems.

This one is saved by the general concept.
Although we want more, and a few answers, if we think beside the box we get there.

It's not a bad drama per se, for judgmental and critical people it is likely to have its numerous flaws.
Still, if you really like bands as much as K-pop groups this is not a bad drama to go to.
Just focus on the five elements of the band and their own development. Believe me, it's the best part.
