I don't mind if the movie has a happy ending or it's just a sad story because the favourite couple doesn't end together... I think this could have been a great movie but Han Sol/Eun Sung story was left aside, and it is very important that we could understand what happened in this "love triangle" by the view of Eun Sung and why not Han Sol either...
I have always been an admirer of Korean actors but for some reason I never empathized with Han So Hee, I hope she gets the help she needs because above all she is a human being and all the anger that generated this situation will certainly not bring happiness to anyone...
you can watch it here ;)
