"As I grew older, I realized that age wasn't soaking into me... rather, I was adjusting myself to my age." What a powerful line, and so relatable.

This is a masterpiece of a drama. I expected a lot of romance and fluff but I was pleasantly surprised by the raw realism, the emotion, and the human experiences portrayed here. This drama shows you how love isn't just hugs, kisses or yearning, that it matures with years, and is more about being open and honest with each other, and understanding each other than anything else.

I loved the subject matter more than anything else; difficulties in relationships, a parent's love for a child, dangers of hiding your feelings and lacking communication, youth, friendship, caring for each other, and learning to step into each other's shoes.

The acting was top notch. There's no one who can rival Jang Nara in her ability to make you cry when she cries. The other actors were all amazing as well.

I think the only thing that would be a weakness in the drama would be the explanation behind the time-travel, which is barely even considered as something worth an explanation, till the last 3 minutes of the last episode. But I think one can let go of such things, because it's the content and the subject matter that was much more important in this case, than technicalities.

This drama made me cry and laugh and smile, and I highly recommend it to anyone who is hesitating to watch this.
