The start of the drama raised my expectations high but the last few minutes were beyond me. Apart from that it was overall a good one. The first impulse on seeing the show is to compare it with the soundtrack 1 but that would not do justice to this one. That soundtrack had a different universe this one has a different one. Maybe it was the fear of this comparison only that the writers and the directors tried to give this one a haphazard happy ending.

The beginning really served the ex-lovers troupe where the two leads meet again after a long time with their changed situations. Everything was amazing honestly the characters, the emotions, the setup everything. Especially the chemistry between the leads goodness I wonder what a good execution could have brought out of the gem of this chemistry.
The plot development tried to show how just getting back together is not the endgame for the leads and even if they do get together the breaking apart can happen again if there is no clarity on the character's part about what they did and why they did what they did and what do they want. However, they did not answer any of it they did not even show the female lead side of the story of why they broke up in the past properly.

Also, there was no need to put that poor second male lead i mean the lead characters already had enough of their problems to work on and I don't think either of them cared about poor K. (I didn't even feel bad for him. He was very extra.)

The last fifteen minutes did not make a single sense to me, everything was so rushed I wondered if I skipped something important.
it's not important to give a happy ending, where the leads always end up together to make a good drama.
Personally, I would have felt much better if she had gone to Santiago all alone and discovered herself even if that meant them not ending up together. Her just accepting the male leads company on her Santiago trip defeats the whole point of going there since she wanted to learn about herself and love things just the way they are without letting her inferiority come in between. It was so very unsettling.
Like what's the point of sending her on a trip, closing the shop and breaking up again if that's how they were going to end it, she could have just done that in Korea only why spend so much money. A trip like that will not help her.

I think I took this a little personally but was kinda self-destructive and contradictory.
