older FL version goes into past and destroyed Younger FL's first Love
Your FL doesn't love ML or even notice him, Her first Love was always SML which was forced to breakup by older FL
which i find disturbing
adding SML even after they grown up, is dragging a love triangle which doesn't even have any hope for SML
Younger FL feelings were dismissed and neglected by her older self and forced her love on younger version

I have no problem with ML and Fl being together , i got this is light hearted but Love triangle make no sense
there is no need after she broke up with him peacefully
why dragging SML ? because there is no other story then love and a kidnapper is promoted to killer

reduced my ratings from 9.5 to 6.5 after watching ep 12 and 13
this was a good drama and it should have ended withing 10 to max 12 episodes, but for more money they will drama four Hour they don't even have any story for that, they don't even have 2nd lead couple neither they want to give screen time to her brother and besties love story,
ML and FL are good to look at but they are being forced together that is showing on there face
all chemistry vanishes after they finally had a proper kiss, that all there love was One kiss and after that there chemistry just leave the planet..
and drama try to become some confusing time traveling epic but its just a mess, when writers don't have any story they are just filling 4 hour to get some commercials
it stared very well then like every other Kdrama it went downhill from mid of the show....
common thing between most of Kdramas
