This is my all time favorite drama, so I decided to write a review.
I picked up this story because I’m into some of its tropes, but ended up completely surprised. More than just a simple teacher-student love story, this is a drama that’ll never go the way you expect it. The cast did a wonderful job portraying the humanity of the characters, there are no perfect people here and many times you’ll probably hate them but then maybe you’ll feel huge empathy for them, or at least they’ll show you different sides of human nature.
What’s love and what are its boundaries? Do I love this person or do I need them to feel better about myself? Do I have a right to be selfish under certain circumstances? These are some of the questions this story makes you reflect on; in a mixture of sweet moments between the main characters, cruel realities and heartbreaking situations.
Sometimes I still go and watch my favorite episodes (which is unusual as I don’t usually rewatch dramas), so it’s definitely a drama I recommend.

Note: I watched the older one too (1993) after watching this one, so it’s not totally necessary to watch one to understand the other and I like the 2003 version way more, but it’ll help you see more of some characters stories if you’re interested in them.
