If you've watched enough kdramas (and read shoujo manga), then this is already very familiar to you. Hardworking and cheerful girl gets into hard times and must live with a bunch of good-looking men. Main guy is cold but eventually warms up. Other guys end up liking our main heroine too. That's the set-up.

If you miss these kinds of stories, are fine without getting any plot surprises, and like any of the leads here—then this may be for you. I really like the songs featured in the series. And it's nice that each idol has his own story arc and issues to resolve, separate from our heroine. The show's greatest strength may also be its short length (at 12 episodes only).

On the downside, I don't like some of this drama's use of old-style "comedy" (like accidentally spitting out drinks unto someone's face or shirt). I don't like some of the shortcuts they used too like the CEO basically acting as the manager for the band (this should be two separate roles).

This show uses all the main elements of 2009's You Are Beautiful but minus the charm, wit and originality of YAB. I watched YAB for the first time a few months ago and I was surprised at how fresh the script felt considering the show's actual age (12 years). If you haven't watched that yet, I strongly suggest you watch that first.

Let Me Be Your Knight is alright. It has nice colors and catchy music. But it won't go down as a fun, rewatchable classic like YAB.
