Joseon ML(past ML) is dead then FL came to current world time, finds looks like late husband ML (modern version) Both fall in love,

And then FL went back to Joseon time , before Joseon ML dying, FL and Joseon ML conversation about together in past or back to Current timeline with Modern ML.

BASICALLY FL left his dying husband ML for modern ML. 

Not satisfied with this , technically both ML is different person with same looks and same ideology for FL

This drama is about Joseon FL went to modern timing where she meet Modern ML Who look likes her last Joseon husband. Both fall in love..... But downfall last 2eps.

------------------------

They should only focus on Joseon FL and Modern ML. Instead they done last important 11, 12 ep shown FL and Joseon ML Scenes more in the end. While modern ML waiting for FL
