2. Work Tomorrow Plot Summary

5. Original vs. Drama, Which Are You Looking Forward To?

The real highlight is the cast. As for Seo In-guk, ever since the casting announcement... It's like the male lead from the original work just popped out. Expectations were high for her synchronization with Kang Si-woo to the point where people were saying that, and interest is also focused on how delicately Park Ji-hyun will portray the character Ji-yoon, thanks to the emotional acting skills she demonstrated in *Yumi's Cells* and *The Youngest Son of a Chaebol*.

The original work is criticized for being disappointing due to unresolved plot points, such as the background of Kang Si-woo's divorce. There was a part like that, and this time, the part that original fans are most looking forward to is how convincingly the actors, including Seo In-guk and Park Ji-hyun, will fill in this through their acting.
