Ok!!! I realize how the wrap up may happen. All the characters know part stories so when the other halves are revealed, they’d make the connection.
As this episode opens, Choi Yoon is shown at the school with the bodyguard, Luna (who is evil behind his back). He is here to see his daughter but Shi Won sees them arriving and asks the man for some time on behalf on Seon Ah. Seems like her birth name is Young.
Unable to see his daughter, Shi Won questions the man, whether he knew that Wang group wanted to kidnap Seon Ah to reveal the truth to her. Shi Won reveal as much as he knows to bring the right things to light. The man is smart and brushes it off as simple concern in front of Luna, the evil lady bodyguard.
Hwang comes to meet Shim Bong San and realizes the whole truth. On the other hand Sun Ah also clams down enough to forgive her adoptive father and raise questions of her own. She also visits the condition of the classes which seem to be getting worse. She also sees Shi Won taking a stand for the class.
Chi Ang asks his father for the whole truth with a seriousness that makes the man reveals his suspicion about the location of the keys and his plans. Though he says that he wasn’t behind the fire and give a part of the key to Chi Ang to instigate trust, there is still mistrust brewing as he still seem to be using his son as a tool.
On the other hand, Soon Deok comes to know the truth through her father. She leaves the note to Seon Ah explaining that the two are brother and sister. Even though they are appalled and confused, they make the connection through their memories and lullaby.
On the other hand, Choi Yoon follows Luna secretly. Chi Ang is also confused as he has to keep the promise to his father in order for his mother to be happy.
Hwang is in trouble and I am suspecting the chairman. Because he was the only man who knew that Hwang wanted to meet Choi Yoon in secret. And Bam!!!!! I am right. Yoon suddenly recollects his memories of the night of the fire and it looks like the chairman was the culprit who joined hands with Wang Hao.
Choi Yoon reaches just in time as Hwang gets attacked. Luna tries to stab Yoon but Hwang stands in the way and gets hurt instead. Then, he lets the man know about his son.
Sun Ah also feels the power draw to her as she realizes the hidden location of the second piece.
By the end of the episode, everybody knows that the two are sibilings and they pendent around Shi Won’s neck is the third piece of key. Unluckily it is with Soon Deok now, who has left.
Meanwhile, the two 18 years old best friends also turn up at school while the meditation teacher is madly looking for the key in Shi Won’s room. The action scenes are terrific. And everybody is going to be in trouble in the next episode for being wrong and Soon Deok is going to be in trouble for having the key.
It still stands to be determined, whether Chi Ang will will choose his friends or his father in the end.
