Moonbyul, along with her 3 adopted sisters; Solar, Wheein and Hwasa moved to Seol. It was their first time visiting the busy city after being part of the Kim Family. The  Kims were very delighted when they saw the 4 girls for the first time, in a little orphanage. 

The 4 young ladies along with the Kims moved to the big city when, the main branch of their family  finally lost at the court and hence, Byul's adopted family was given the riches that they had deserved for the pass 3 decades. 

Upon, being there, Byul noticed an all too familiar boy whom she befriended but a big fire drifted them apart. Byul was shocked as the boy whom he remembered was now an idol! And he can't seem to remember her, instead he could only remember Solar!
