Smile, Dong-hae) is a 2010 South Korean daily television drama, starring Ji Chang-wook, Do Ji-won, Oh Ji-eun, Park Jung-ah and Lee Jang-woo.

It aired on Korean Broadcasting System's premier channel KBS1 from October 4, 2010 to May 13, 2011 on Mondays to Fridays at 20:25 (KST) for 159 episodes.

Although Dong-baek survived, she suffered brain damage, erasing her past memories and left with the mental capacity of a nine-year-old.

As a young adult, she fell in love with a Korean man, who used the English name James (aka Kim Joon), while he was studying abroad in New York.

Carl/Dong-hae visits Korea with his mother to participate in the short track speed skating competition as a representative on the American team.

Because of how Do-jin grew up, he doesn't want to date someone who had a relationship before, having an unusual logic that a woman with an ex-boyfriend would unfaithfully think about their former partner rather than their current one.

Sae-hwa wanted to marry into the Kim family and lied about being an inexperienced girl that was too busy studying to date anyone.

Learning of Dong-hae's paternity to James, she did her best to make sure the Lakers didn't get too close to the Kim family to avoid discovery.

Because of the complications of reuniting as father and son, James kept his identity a secret to Dong-hae, but use his excuse as an executive to spend time with him.

The Lees at the time were financially tied to the Camellia Hotel in their kimchi business, Hye-sook intends to hurt anyone that ever cared for the Lakers in retaliation, forcing James to stay put.

He left a letter, explaining his reasons for leaving, but he promised this isn't a goodbye; he intends to return and wants her to wait for him.

Dong-hae was a budding celebrity chef and secretly worked at a friend's restaurant to help make ends meet.

During this whole time, both Do-jin and Hye-sook grew cold and weary of Sae-hwa; they both wanted her out of their lives and insisted on a divorce.

Not willing to give up on Do-jin, she summoned the Chos back into the hotel, causing blackmail and pressure to prevent herself from getting divorced.

If Anna would to come back, Mr. Cho would never transfer his majority shares to Hye-sook and she'll only be an executive for the rest of her life.

Mr. Cho discovered the Kim family was fragmented due to James' past relationship with Anna and tried to pressure him to stay with Hye-sook.

Sae-hwa managed to figure out that Anna and Dong-hae are related to the Chos and did everything in her power to use this information as a bargaining chip to keep her within the Kim family.

Sae-hwa eventually grew tired of trying to win back Do-jin and she granted him the signed divorce papers.

Because James felt responsible for what happened to his daughter-in-law, he made the effort to look after her and she repaid his kindness by occasionally tipping him off about the devious machinations of his wife and son.

During Dong-hae's and Bong-yi's wedding, Do-jin called for an emergency stockholders' meeting to talk about the future management of the hotel.

Dong-yi secretly discovered a calculation mistake in the hotel's finances and tipped off the authorities of tax fraud.

With everything right in the world, Dong-hae re-proposed to Bong-yi (after the health scare with his grandfather) and the two successfully carried out their marriage without a hitch this time.
