I understand who people might be unhappy with the ending or not like the show as a whole. It’s not a masterpiece but I did like it more than I thought I would.

It is a story about love. It’s just not the love we were expecting. It’s a story about love for your family. The dad expresses it well when say that he’s happy the mom died without finding out about the daughter and Ji Won. He loved her so much that he was happy he died that day and not on the next, for example. The same way that Ji Won knew that Naoko loved him very much, but he liked her enough to let her be free and loved his mom so much that he’d always choose to be by her side.

I specially like the ending. We see that both Ji Won and Naoko appear to be happy. Also like how Naoko chose not to tell about her mom passing. They cared about each other until the end. Nice to see the sister hanging with the basketball guy and studying.
