One of the best movies I've watched in 2020. Such a lovely and heartwarming story. The plot and the message behind it was great in my opinion. This was a remake of a K-drama, but I can tell this is much better. It was not just another high school love story. It conveys a lot more beautiful messages, about family love, friendship, depression, life meaning, etc. I never wrote a review before, but I decided that I had to get my lazy body to type this review to pay respect for it.
Tl;dr: Watch it, you won't regret! And to the stranger who is reading my comment, I wish you would have all the beautiful and great things happen to you!
