Let Me Be Your Knight (2021) Review


“Let Me Be Your Knight” is a work depicting a sweet and bloody, mental healing romance between a world star idol who suffers from sleepwalking and a medical doctor who has to secretly treat it.

In the character poster released on this day, Jung In-sun, who played the role of In-Yun-Ju, a girl who disguised herself as a resident doctor, Lee Joon-Young as Yoon Tae-In, Jang Dong-Joo as Seo Woo-Yeon, Kim Jong-Hyeon as Lee Shin, Yoon Ji-Sung as Kim Yu-Chan and Kim Dong-Hyun, who played the role of Woo Ga On,  the Luna band’s member (five-members band).

In particular, the copies representing each character in response to the question about ‘music’ in the poster arouse curiosity about what kind of personality and story they each have.

First of all, In Yoon-Joo. a girl who doesn’t know about ‘music’ but has to live together with the world-famous idols and as a musical genius’s primary care physician! In Yoon-Joo, known as an idol in the tourism, self-recognized filial piety industry, and is a healing doctor. That raises questions about what kind of story she has and became Yoon Tae-in’s resident doctor.

Yoon Tae-in, the leader of the band Luna and who will receive mental treatment from In Yoon-Joo. Yoon Tae In is an untouchable idol star who is loved all around the world, and a musical genius who believes he is the center of the universe. “Music is as natural as breathing. Because that will happen soon,” he said, showing the confidence of a genius music producer.

By accident, different characters meet and live in one house, raising expectations about what kind of ‘chemistry’ they will present.

In the released poster, Jeong In-sun and the band ‘Luna’ are standing side by side on a large keyboard and smiling brightly. Their bright laughter radiates bright energy, making even the viewers happy. Another poster shows Jung In Sun and the five people band LUNA walking side by side, holding instruments against the night sky with the old moon in the background.

This raises expectations for the colorful healing music in the drama ”Let Me Be Your Knight” which is a music drama, as well as the chaotic episodes and growing up that In Yoon-Ju (Jung In Sun), who lives in the same house with the world star idol band Luna, will experience.

As such, ”Let Me Be Your Knight” plans to provide a time of laughter and healing to the small screen as the characters with distinct personalities grow up.
