I'm conflicted about the ending. Mostly, I enjoyed it because the actors sold the drama, but the writers put too many characters into the storyline, and the "unequivocal love" was a waste at the end. **SPOILER** The two main characters have a complicated emotional relationship. After enduring and embracing each other's hardships together, they have a lot in common despite their age difference. In the end, he and his wife are still together: yet, she and their son are living in the US now while he stays in Seoul. He seems to keep his promise and is living a happy life as a CEO, and she has found peace in her new life. Both have grown together and separately with great admiration for one another. It was an okay ending, but they may have well never seen each other again and just kept tabs on each other through mutual friends. Although you see a possible rekindle deep emotions through a small hand gesture and eye contact, it's just left up to your imagination.
