Seulbi tried her best to save Sookwang. She managed to turn back time and save him but in return, she suddenly vanished and all that was left was her necklace.
After that, Sookwang devoted his time searching for Seulbi.
Even Minjoon, and their friends from the market helped but to no avail, they still couldn't find her.
Winter came but they still couldn't find Seulbi.
After trying and following any leads that they could get, Sookwang finally found Seulbi. She is living a normal life but she has lost all her memories and is now living as Gyeongja.
Sookwang tried to take Seulbi back but she didn't believe him right away as she told him that many already came claiming that they are his older brother, boyfriend, or even her husband.
As expected, Sookwang didn't give up right away. He tried to stay by Seulbi's side and followed her as much as he can.
What made Seulbi finally listen to Sookwang's story was when he started talking about the gummy worms. She also noticed the ring that they were both wearing.
Seulbi heard everything from Sookwang and she finally came back with him at the Geumhwa Hotel. There she was re-introduced to her brother Minjoon and his fiance Jang Kyung.
Sookwang gave Seulbi a tour at her room to help her try to remember but to no avail, she still couldn't remember even her Mom.
Their next stop was at the Seodong Market where they also tried their best to help Seulbi remember her memories. They re-enacted all their fond memories but it still didn't work.
After meeting the people at the Market, they went to Sookwang's house where they lived together before. Seulbi still couldn't remember anything but her mischievous side came out when she teased Sookwang and asked him if they kissed before.
Sookwang was about to kiss her but she stopped him saying that it feels like he's showing off after kissing another woman because she can't remember anything.
Now that he found Seulbi, Sookwang didn't waste any time and asked Seulbi to marry him. To this, Seulbi answered him with a kiss.
At last, it's D-Day for Sookwang and Seulbi's wedding. Everyone was in festive mood, and although there was a very small accident, the two happily sealed their special day with a kiss.
Fast forward, we see Seulbi and Sookwang living a happy and normal life. They now have a son named Sihyeon. Although Seulbi's memories didn't return, Sookwang says that he is now living with a prettier wife.
But wait, there's more! We go five years later, and it seems that Seulbi finally got her memories back as She found the words "I Love You" which they wrote on the stones before.
