Story wise, this really isn't new or innovative at all. I have watched 200 Pound Beauty which seems to be the ORIGINAL 'weight-loss' story. I haven't watched Birth of A Beauty which seems to be the most recent and alike incarnation of this storyline. How the story tried to separate this show from others, and which it did quite well, is to emphasize the health aspect of weight loss, as opposed to the beauty aspect. The show doesn't try to shout this at you, but it's so imbued in the characters that you just get it. The antagonists aren't very antagonistic and don't pose much of a threat to the lead characters. That's both a credit to the writing of both the antagonists and leading couple. What I really love about the leading couple is their strength, their maturity. No unnecessary angst, mother-in-law drama or dead-fish kisses here. It's enhanced so much by the chemistry and ease between Shin Mina and So Ji Sub. There really isn't much happening story-wise, and this is where the cast saves it from becoming a snooze fest. Shin Mina and So Ji Sub feel very comfortable with each other and it really adds to their fantastic chemistry as a leading couple. It's my first time watching Yoo In-young and I really like what she did with an otherwise tepid character. There's really nothing much to comment on Jung Kyeo-woon, because it seems he was given very little material to work with. Overall, a pretty light and uplifting drama, but somewhat forgettable.
