In this strange world, Jin and Joon each meet familiar friends and foe before reuniting to embark on a new mission - to fix Halmoni's magic pot that Joon broke back at the house. Will Jin and Joon succeed in restoring Halmoni's magic pot? And will Halmoni forgive Joon for having broken her favourite magic pot in the first place? This story is about the children's courage to face their fears and their efforts to do the right thing, and how love makes it all possible.
