@ccc so mi-eum was appointed as a spy to spy on jitae....in exchange jitae's brother promised to find mi-eum's father. But later he betrayed mi-eum so jitae and mi-eum made a deal . Later we will know that both already met eachother in an incident caused by mi-eum's father. His father possibly kidnapped jitae and mi-eum saved him that time. Hope it makes sense
