Thanks for sharing May, just read that early this morning. I've seen all of writer Ha Myung-hee's dramas and enjoyed each of them. "Temperature of Love" is based on writer Ha's book titled “Chakhan Seupeuneun Jeonhwareul Bakji Anneunda”. I have no idea what the translation is, perhaps a kisskh fan/reader can translate that for us.
As to Seo Hyun-jin, she's a marvelous actress that I've followed since watching "Feast of the Gods" in 2011. I hope she accepts this role and I'm excited to see future casting.

Just saw a preview in the theater, and waiting for the USA premiere on June 15th.

According to a June 13 post on Soompi, Jang Mi-kwan has withdrawn from the drama. On June 13, the chief producer of “Best Delivery People” said, “Jang Mi Kwan will be leaving the cast.” He explained that this was because there were some disagreements while working out details.

You're welcome, and thank you.

He confirmed!

Yeo Jin-goo and Lee Yeon-hee confirmed as leads. From Writer/PD team of "Beautiful Gong Shim", "Girl Who Sees Smells". Jung Chae-yeon (Drinking Solo) will play Lee Yeon-hee's teenage character.

Interesting, the lead actor and actress were born in the same year. Namgoong Min in March of '78 and Uhm Ji-won in December of '78.

That's a good question and I wondered about it too. The actress that accepted the role, Uhm Ji-won, is a talented actress. And from reading the broadened synopsis from Dramabeans today, I think Uhm Ji-won can bring a lot to this role. Guess, we will have to wait and see to be sure.

I certainly hope so. I really enjoyed "Clinic On the Sea".

I was wondering the same. Have to wait and see unless we get more details shared. I'm keeping an eye on Dramabeans for updates. Here's their most recent blog if you're interested.
