As this episode kicks off, Chi Ang cuts his friendship ties with Shi Won and tells the secretary to find Soon Deok because she has the key. (I am screaming in my head- stupid move chi Ang). Though he also threatens the man, not to lay a finger on his girl, still, stupid move.
Anyways, The bad professors and dean leave the school after being humiliated (just a little) and Seon Ah makes up with both her dads.
Meanwhile, Shi Won goes to find Soon Deok and Chi Ang’s men follow. Eventually, both get to her. It is then we realize that both men are tryting to protect the people around them in their own way. Chi Ang is doing so by trying to acquire his father’s power while Shi Won is doing so by giving up power. His father is just a bad person who accepts to using his son and kicks the Beop Gong aside (you had it coming, you traitor)
While Chi Ang takes the third piece of the key, Shi Won takes Soon Deok back to school where everyone is preparing for a possible attack. Shi Won and his father also have teary reunion.
Finally we see a flashback of what happened when the two went to find Soon Deok. Shi Won gave up the key with trust that his friend would do the right thing. And in spite of everyone’s warning, he hands over the last part as well.
Wang Hao is surprised to see the complete key but Chi Ang doesn’t give it up. In stead, he jumps from the cliff with the key. His father jumps after him to save him.
After 7 years of that incident, Soon Deok has become the Dean and Soon Deok, teaches there. Shi Won is a famous singer while Chi Ang runs his father’s company. They are all friends still. Also, surprisingly, Chi Ang and Seon Ah have got together and plan to reveal it to their parents soon. While Soon Deok and Shi Won are handing out their wedding invitations. Other students are also set with their career. I am only dissatisfied to not know what happened to all the bad characters because they surely didn’t die.
We see a tiny flashback again. Shi Won saves Chi Ang and his father from the falling cliff by his energy. They went to the cave in Moorim Peak to find the Chintamani before destroying the key. Funny thing is, that it was just a reflecting stone. Like the mirror scroll in Kung Fu Panda. It means the power is withing you. But the two do not open the secret to others.
