This drama have truly original and beautiful story. It shows struggles many of us had during growing up and that life is not just unicorns and rainbows. It's shows more realistic side of life. Also the fact that they were able to show years passing in such a great way even thinking about changing phones or apps they were using. Great idea. It is a BL but I didn't feel that intense romantic mood between actors. They could work a little bit more on music and showing how each character came to an understanding of their feelings for each other. I felt that it was not that well presented from perspective of every character. If not for that then I would consider this series one of the best.
