"Mom Has an Affair" has a good story line, however, it lacks on-screen chemistry between the male leading actor and the female leading actress that portray Kang Seok Jun (actor Lee Jae-Hwang ) and Oh Pil Jung (actress Hyun Jyu-Ni). There is no intense eye-contact between these two leading characters. The sweet on-screen chemistry develops between the second leading characters, Oh Sun Jung (actress Nam I-An) and Lee Tae Woo (actor Seo Hyun-Suk), they steal and save the show. Also, the tender heart character Chief Surgeon Choi Dong-Seok (actor Kim Dong-Gyun) helps catalyzing the story line when it is needed.

It is heart wrenching to watch Leon/Jumbak, the pet dog looks so lethargic for the whole 122 episodes. I just hope the “humane” Animal welfare guidelines are followed by the studio that produced "Mom Has an Affair". Leon becomes a lifeless ornament in the show, it is distressing to watch.
