Lee Hyun-woo was very, very wooden in "Masters of Study", he was a bit better in "Equator Man".

Jung Yoo-jin, as a non-actress, did a reasonable job in "Grapevine", her role definitely not an easy one (it helped that Baek Ji-yeon, who played her mother and was her primary acting partner, is a non-actress too). Not sure about her range though.

Hongbin was just plain terrible in both roles I've seen him.

Seo Ye-ji, compared to the other three, might actually be the most solid actress relatively speaking. She's still very far away from being lead material. She's a schematic actress, a style that needs a lot of experience behind it to make it work, which she hasn't.

Overall: Very risky line-up, especially for a prime time show.

And because dramaland has finally given Hyunwoo oppa, I will forgive the inclusion of the other "actors". After all, oppa will surely shine even brighter, thanks to the other three. He is more than enough reason to watch ?????

Congrats to his first drama as the lead ?? This would have been the best welcome to 2016 had Sungjae oppa chose this over Village, but I'm happy for both LHW and YSJ ??

I can't wait

Conflicted. I dont like the lead girl but I loooooooove Hyun Woo.

I cannot get over how much this guy looks like Park Bo Gum, and vice versa.

Ehhh about the cast but it's him so now we all have to check it out... mega big sigh..

I had already wrote Murim School off once they casted Seo Ye Ji and HongBin last week, but now I'm back onboard. I will watch this solely for Lee Hyun Woo and try to ignore the other talentless leads, while hoping Lee Hyun Woo ends up with Jung Yoo Jin (whom I've never seen act, but heard Heard It Through the Grapevine was an ensemble project) instead of Seo Ye Ji.

Honestly? I would like to see him in a drama other than a high school one. His past dramas were more or less about high school: "To the Beautiful You" (where he was the only good thing about it, and I wish I hadn't wasted 16 hours of my life on that drama) and "Master of Study" which I dropped after episode 5 for being gut-wrenchingly boring.

I know he's done cameos in other dramas recently and I was looking forward to watching him in another drama, but if it is about high school, I may have to pass. There have been so many high school dramas in kdramaland lately. It feels like a glut. Kind of how Time Travel flooded kdrama land in 2012.

The premise for this drama is sounding more and more like a mashup of "Dream High" (with Lee Hyun Woo being the Go Hye Me of "Murim" to boot), Heirs (with Seo Ye-ji being the "Murim" version of Eun Sang), and School 2013 (with all dat bromance that will ensue) ....

Don't forget Monstar "prickly, stuck up guy in top idol group"

I'm experiencing flashbacks of him in To The Beautiful You, but that was ages ago, pretty sure he's alot better now. This casting reminds me a bit of what happened with Kill Me Heal Me where the cast kept on changing for awhile, but in the end we got a pretty decent drama. Then again we could be experiencing something like that Marmalade drama which Yeo Jin Goo hard carried, can't tell for sure.

It makes me wonder why he picked this drama, because he can always do high school dramas with his baby face. He's only 22 years old! I was reminded of recently reading an article on soompi regarding why Park Hae Jin took on the Cheese in Trap role. He mentioned that he's actually rejected the script several times, but ultimately took on the role. The reason being he's in his 30s, so it will most likely be his last chance to play a university role. I found this reason quite fitting, but it definitely doesn't apply to Hyun-woo.

I feel so torn because I love him to bits, but the drama doesn't sound promising..

He's so adorable, just wanna pinch pull those cutie pie cheeks -

Imma do it for Lee Hyun Woo..and if it's bad BYEEE
