The synopsis alone is very telling as it doesn’t try to hide the fact it is largely based on recycled tropes. Approaching it with this awareness can prevent disappointment, as the series doesn't strive to be more than a brief and easy-to-enjoy watch.

The drama commendably portrays the challenges of being a musician, especially within the K-pop industry, shedding light on the sacrifices idols make, such as compromising their privacy and love lives.
The music aspect is remarkable. For me, this is what I enjoyed about LMBYK the most. I listen to the songs still after completing it.

However, certain elements seemed less believable, though given the drama's premise, this isn't entirely surprising. The characters, especially the main lead, were often insufferable, possibly conforming to the bad-boy cliché. The female lead didn't fare much better. The side characters, though not seasoned actors, brought a cute and funny dynamic, understandable since many are retired idols. I wish the couple got a better closure.

In conclusion, Let Me Be Your Knight" can be an enjoyable experience if you approach it with the right expectations.
