The first part, in their teens or high school years was done very well. There was too much of parental expectation stuff, and of class differences in Korean society.

The second part, which has a reversal of fortunes, was not done too well. For one thing, I don't understand why they had to change the actors. People don't look completely different from when they are 18 and when they are 30. But the initial part of the story was touching and that is what I will remember this story for.

There was also a sad episode where the only reason for their separation was a note that was not delivered. Eventually, both of them thought the other had ditched them, all because of an undelivered note and a misunderstanding. But then, so many dramas are based on minor misunderstandings..

As so often happens, I went to re-watch the drama, and saw it has disappeared from Netflix. I will probably never see it again.
