I don't want to Lower my score because that would be too unfair for the magnificent acting of the cast, ESPECIALLY the main couple's, the amazing cinematography and story (for most episodes) BUT... but...

The point of the show is how we mature through our experiences and relationships (especially first love). The problem is that the main leads never overcame their relationship with each other. They still have feelings for each other and regrets till the end of the show (present), which nullifies the whole point of the story!!! I hate sad endings in general, but I hate them even more when they exist just to exist without actually contributing anything to the story. If they had at least moved on, it would have been a better ending, a sad but nonetheless well made ending, which unfortunately, for me, it was not.

Also mature doesn't equal miserable and filled with regrets. But that's exactly what I got from this ending. Some relationships are worth fighting for... they're not just stages that lead to our "miserable" adult life... People can be successful both in their professional lifes and in their relationships. We don't need to sacrifice either of them for the sake of the other...

All in all I loved the first 13 (more or less) episodes but I cannot find the ending ideal nor realistic, which ruins the story for me. People express love differently but I cannot fathom 2 people loving each other so much, in a resolvable situation, instead of trying to work things out, they just break up. Both relationships and work alike require effort to maintain.
