......I was wondering that too. While they were crying on the porch I was waiting for Doram to say ""I know Do-un, how about you come with me and live in the Palace too'''
------but it never happened :(. ..
I was kind of hoping
Do-un would go to the palace and marry the Crown Princes sister and then Doram and Lee Hyo can retire to live in the small cottage Doram wished for in episode 25.
....WHOAA!! Holymoly Josieb, that's an intricate plan you stated and probably the BEST.
Do-un would make a fine Emperor-Consort (?) whatever that title may be.
Why did he not take little bro back to the palace with him? : (
