Don't get me wrong, I love Lee Seo-won but Ha Ji-won is basically babysitting at this point.

I love Lee Seo-won in The Liar and His Lover, but he is so baby-faced that he must be playing a medical geeeeeenius.

Kang Min-hyu and Lee Seo-won in the same show. cuteness overload!

Lee Seo-won does have an attractively deep voice which could add some maturity to his actual years.
I do wonder about all the young casting in dramas. Nam Ji-hyun is 21 and is playing a lawyer in Suspicious Partner. At least the young casting goes both ways, female and male.
I can't imagine a love line with Ha Ji-won at all. Maybe some more casting will come out. How about a mature male nurse?

Lee Seo Won was great as the bassist/composer in the Liar and his Lover so it seems like this new addition to Hospital Ship will make it a very cute show. However, I'm not really comfortable if there will be a loveline between Ha Ji Won and her two young costars. It just doesn't seem right in my personal opinion, but hey, who knows.

So. Many. Babies. :o I don't even know what to think anymore. :D
Happy for my Chan Young-aa though! ^^

I liked Lee Seo Won in TLAHL but I can only see this working if Ha Ji Won is the leader of the medical team, as a mentor to the young'uns.

Best case scenario: she's already married and her husband is left pining on shore (take your pick for cameos).

Dang it. I have no plans on watching this. I guess, I'll probably just try the first episode since he is going to be on board this ship.

I had second lead syndrome in TLAHL because of this guy. I'm really looking forward to this show now!

I wasnt gonna watch this show. Guess I have to now that Lee Seo Won is on board!

I loved Lee Seo Won in The Liar and His Lover! Even though in the beginning I only thought of him as a selfish jerk, I loved him at the end of it. Fighting, Lee Seo Won!!!

My personal feeling is that both Kang Min Hyuk and Lee Seo Won look too young to be playing doctors . Maybe they'll age them up with make up and styling? I can't unsee them as high school teenagers from their past projects, so the leap to doctor is a stretch for me.

Speaking of which this has the feel of an idol drama, will there be any seasoned veteran actors signing up for this drama apart from Ha Ji Won?

I loved with him in "The Liar and His Lover" so i'm looking forward to his new drama.

This kiddo is just so cute.

Ha Ji Won looks so miscast now. What are they trying to go for with this drama?

I quite like LSW after seeing him in Uncontrollably Fond. Haven't seen The Liar and The Lover yet. I might check this out since I also like HJW and KMH.

The drama title should be more like Hospital ApprenticeShip!

After seeing him in TLAHL even if I never completed the whole drama, I can now see why he would have been a perfect fit for the school series. Bummer.

I actually hated his acting in Liar and the Lover. He seemed insincere when delivering his lines. His character always came off as fake to me, so I'm not really looking forward to his role. But besides that, what's going on with the casting here? Why are they surrounding HJW with these baby-faces. If the guys aren't interns or something, I'm going to have a hard time believing it.

i love lee seo won, but i can't see him playing a doctor just yet. he's so young and he looks young. can he actually pull it off?

at this point, only ha ji won would look convincing as a doctor. kang min hyuk also looks so young to be playing one.

Kang Min-Hyuk and Lee Seo-Won we can make a band at this point. Just add some other singers and musicians and this show can be a musical.

He is still too green.

Didn't watch TLHL, but I know he's an actor from Blossom Entertainment and he's a MuBank MC. Seems like he's being groomed to follow Park Bogum's path.

Isn't there a Japanese drama starring Matsuda Shota which has an almost identical premise? Is this an adaptation of that drama?

the casting of this drama reminds me of "Entertainer".. and it's not a good sign.
