A drama detailing the life of King Gwanggaeto the Great, who restored the glory of Goguryeo by wresting power back from Baekje, which had invaded Goguryeo prior to Gwanggaeto's birth and dominated East Asia under the rule of King Geunchogo.

Lee Kang Joo is a single mother who was abandoned by her previous boyfriend, Yoo Ho Nam. Ho Nam forgot that Kang Joo was pregnant with his child and went abroad to study. When Ho Nam returns to Korea, he wants to pick up where he left off his relationship with Kang Joo. However, Kang Joo, is not as willing to start over with Ho Nam. Choi Seung Hun is the son of Jung Soo Hee who is Kang Joo's mentor and boss. He has been pursuing Kang Joo for a while and hits a roadblock when Kang Joo's ex returns.

Jung Min Joo is a woman from a very tough family background. Her mother had three children with three different fathers. However, she overcomes this in order to become a news announcer. When she first meets Kim Joon Sung, she is annoyed with his continued courtship of her. Eventually, Min Joo marries Joon Sung and her life changes. Her aspirations of becoming a great reporter are put on hold while she copes to her new life as the second daughter-in-law of a rich and influential chaebol family.

A comedy romance drama about potential son in-laws who come finding their way to the doorsteps of their future wives because of fate. Jo Gi Dong is a guy who causes some chaotic situations when he aims to become the son in-law of a rich man portrayed by Joo Hyun. Han Mi Soo is a rich girl who falls for Gi Dong. Kim Seung Soo plays Mi Soo's first love in college.

A-mi, for instance, keeps sleeping with her boyfriend Heung-soo, but she knows too well that this rocker-wannabe does not have any real chance to succeed in this tough world where there is no protection whatsoever for talentless men. A-mi willy-nilly stumbles into a better choice — this time, a capable man named Seung-won (Kim Seong-su), who is an accountant for Deloitte’s Seoul office. Except for this guy’s dreadful sense of humor, A-mi vaguely assumes that her life would change for the better if she tied the knot with him.

But what really concerns her is neither of these men. She is, after all, an aspiring screenwriter, and she is determined to finish her first project, no matter what. When it comes to determination and toughness, A-mi is portrayed as a cinematic macho who used to be a hardcore chainsmoker, but resolutely quits cigarettes once she gets serious about her career — a far stronger, almost traditional alpha male...

Even though times change and our relationships with our family changes, our affection for them is timeless. The drama is about affection that is the foundation of family.

Dong Jin then starts a new romance with Eun Ho whom he works with.

Song Il Gook plays Ju-Mong, the founder of the Goguryeo Dynasty in 37 BC. Han Hye Jin plays the role Soh Suh No (소서노) who is extremely intelligent and is King Ju Mong's second wife.
