Plot summary
Wonderful World begins with a small and happy family of psychology professor and author, Eun Soo-Hyun; her courageous and righteous reporter husband, Kang Su-Ho; and their previous young son of five, Kang Gun-Woo.
All changes when Gun-Woo dies in a car accident. The man who hit him, Gwon Ji-Woong, confesses to his crimes and is given an outrageously light sentence, thanks to his political ties with Kim Joon.
Seeing how he has no remorse for his actions, a devastated and disturbed Soo-Hyun runs him over with her car. She goes to jail for killing him, and serves 7 years there, before getting out.
Ji-Woong’s son, Gwon Seon-Yul, begins his revenge against her that he’s been plotting for all this time. He fools her, deceives her, and torments her by causing havoc in her family life.
Later, he and Soo-Hyun come to learn that they have a mutual enemy, and he also realizes that the woman he seeks revenge on is truly a victim like himself. They join hands to take down their mutual enemy, who was key in making both their lives worse.
Ending explained:
Gun-Woo’s murderers
Gwon Ji-Woong ran over Kang Gun-Woo with his car and remained remorseless as he was tried in court and given an offensively light sentence.
However, that’s just what Eun Soo-Hyun and others thought happened, which led to her taking his life in revenge.
The truth of Gun-Woo’s death entailed a different story altogether, which is revealed later on in Wonderful World.
It was Kim Joon who hit Gun-Woo with his car, as he was driving carelessly and while under the influence as well. Instead of taking the poor boy to the hospital, he drove to a remote place.
He then called his trusted man Ji-Woong, and asked him to come over. At the same time, Ji-Woong was with his wife and son Gwon Seon-Yul, who was hospitalized and in dire need of a heart transplant.
Kim Joon opined that he must not let a “little bug” that he crushed stop him from reaching the Blue House, i.e., becoming the president. So he thought it better to quash the bug for good.
Ji-Woong struck a deal with Kim Joon according to which the politician would save his son’s life in exchange for Ji-Woong finishing the job, i.e., killing Gun-Woo for good and taking the blame upon himself.
Kim Joon, meanwhile, came out of the situation spotless and clean and went on to order a hit on Seon-Yul’s mother when he found out that she knew about

She left the tablet at a pawn shop and a clue to find it in the necklace that Seon-Yul kept with him after she went into a coma. Before her death, she woke up momentarily and mentioned the tablet again.
Eun Soo-Hyun tracked down the tablet, saw the evidence of her son’s chilling murder, and went to a police officer with it. When a complaint wouldn’t be registered again Kim Joon because he’s just about to become a president.
However, she uses her status as an author and reveals that she’d be writing a book about the truth of her son’s death and how Kim Joon caused it. Then the media picks it up, albeit still not as enthusiastically as it should.
However, the people do. Many people who have known Soo-Hyun and can attest to her character, support her. Other families of Kim Joon’s victims come forward too.
