After the shock of realizing his family has essentially wiped out Ri Jin's existence to put him in and to hide their act of abuse, Do Hyun looks up with a scary determined face.
In the mean time, little Do Hyun is living in a small village with Joon Pyo and Madam Shin. It is interesting to see that Joo Pyo was actually a really good father to Do Hyun before they went back to the Cha mansion. In fact, little Do Hyun promised to buy his father a boat when Joon Pyo tells his son that his dream is to sail around the world. The father and son agrees to name the boat Perry Park. So does this make Perry Park actually a representation of what Do Hyun imagines his father could have been?
Joon Pyo is stunned when he comes home to find Seo Yeon there with "his" daughter. Joon Pyo tells his dad that there is no way Ri Jin is his since he never touched Seo Yeon. However, Joon Pyo's dad is unmoved (he already knew Ri Jin's father is someone else) and tells him to just let things go if he wants the family to accept little Do Hyun and his mom.
Thanks to Madam Shin's help, Ki Joon's dad is able to release a news report that says Joon Pyo is not likely to recover anytime soon. Increasingly in danger of losing Seung Jin Group, Chairman Seo is surprised when Chae Yeon pays her a visit and tells her that she wants to be with Do Hyun, but in exchange for her family's support Chae Yeon wants Chairman Seo to give Do Hyun the controlling power in the company.
Do Hyun receives a photo from Secretary An that has all the food staff that was at the house the fateful day of the mansion fire. Do Hyun is stunned when he recognizes Mama Oh in the picture.
Do Hyun receives a phone call from Dr. Park informing him of Ri Jin's recent fainting episode and he grimaces in pain as Dr. Park guessed that Ri Jin remembered her past as well.
With shaking hands, Do Hyun puts the flash drive in and immediately sees Ri Jin's smiling face. Do Hyun breaks down in sobs when Ri Jin confesses in the video "I like you, Cha Do Hyun."
Ri On takes Ri Jin out playing with their dog, and as the two laughs, Ri Jin is glad to have a brother who has always been her support.
Standing in front of her son's hospital bed, Chairman Seo tells Do Hyun about the night the fire destroyed the mansion. On the night when his dad was to introduce him to the world as his son, little Do Hyun decides to run away with Ri Jin. Unfortunately, the two kids are caught by Joon Pyo even before they made it out of the basement door.
In fear, little Do Hyun begs his dad not to hit Ri Jin but Joon Pyo just tosses his son out of the door while he goes back into the room with Ri Jin. Do Hyun pounds on the door as little Ri Jin's crying and sounds of things being broken could be heard from the locked room.
Back to the present time for a moment. Chairman Seo stares at Do Hyun and tells him the final piece of the puzzle. "It was you that I saw that night. You were the one that set the fire that made my son like this!"
In shock, Do Hyun runs out of the door only to fall to the floor as his headache overwhelms him again. In the midst of his pain though, Do Hyun's own memory comes back. After little Do Hyun's screaming pleas for his dad to not hurt Ri Jin goes unanswered, the little boy sits down on floor and thinks "This is all my fault!" Little Do Hyun's head suddenly starts to hurt as a voice asks him "Do you want to save her? I will do it for you..." When the little boy looks up again from his pain, a little Se Gi is born.
We end the hour with Ri Jin saying "Shin Se Gi?"
After saying "I am late, I am sorry." Se Gi reaches out his hand and says "let's go."
Okay, I guess all the mystery are finally solved! Well, actually we still need to figure out who killed Chairman Seo's husband and Ri Jin's mother. I am betting my money on Ki Joon's dad although there are some hints that it might be Chairman Seo herself.
It did surprise me that Joon Pyo was actually a good dad to Do Hyun at one time. Actually he looked like he might have been even a nice guy who just wanted a quiet normal life. So I guess another mystery is how he turned into such a monster with no regard even for his own son.
I was a bit surprised the writer brought out Se Gi again, but then I guess left to Do Hyun he probably would have stayed away from Ri Jin because of his guilt. So we kinda need Se Gi who sees nothing else other than Ri Jin.
