first of all, i never felt so comfortable watching a k-drama. like, every episode that i watched i felt like I was having a popsicle on a refreshing, sunny day. the fun, chaotic, youthful energy made me feel good, made me want to be friends with the characters.

speaking of the main song, wow what a good song!! I've never heard an OST so enjoyable to listen to!

and of course, I can't forget sign language, it was a great plot! it was also cool to see some of the korean sign language.
I also can't deny that I was moved in many parts, not only in the sad ones but in the happy ones too!

The only criticisms I have are:

1° they could have shown how On Eun Yu's life turned out after their return to 2023. What happened? What has changed?

2° There could be a part where Ha Yi Chan asks Ha Eun Gyeol how he found the cassette tape of his old song.

3° They could show in detail how Yoon Cheong Ah and Ha Yi Chan's lives changed. We can see it, but not much.

ah, anyways, this k-drama will stay in my thoughts for a long time. I've never seen a drama like this! it was a refreshing experience ?
