What did u get disappointed with?

I was disappointed that they never revealed when Seo Do-guk (ml) fell in love with Han Yi-joo (fl) because before they went back to the past he was already in love with her as far as it seemed unless i got it wrong…

But Seo Do-guk said to Han Yo-joo’s ex fiancé he has loved her for a long time and that she can use him… 

Last half of episode 11 and episode 12 i feel were just drag they could have used last half of episode 11 or first half of episode 12 to get that story in.. 

another thing is no one even once gave it a thought that when fl’s step-sister said then im the fake.. Han Yo-joo was a bit puzzled but I’m surprised it didn’t even hit her to think about it.. or look into it they had 1 1/2 episode yet 2 things were never unfolded😒

Exactly they try to Cut the drama short 13 episodes instead of 16 from being dragged but honestly last 1 1/2 episode was a drag 2 important things were never revealed 

i really really wanted to know when and how ml fell in love with fl and also even if step-sister didn’t go into her mother’s evil steps it should have revealed that she was not even the bloodline of fl’s family… how can they miss such 2 important things 🤦🏻‍♀️
