I really enjoyed this drama for many reasons. Whilst I think their portrayal of deaf people could have been better (e.g. usually deaf people still make sounds and especially someone that lost their hearing later in life could still speak on occasion) I do agree they went with the most respectful route. Had they tried to imitate the way deaf people speak, I feel that it may have come across as offensive as the actors are not actually deaf.

I also think the ending was rushed. I was excited when it was mentioned in ep 14 that they would be returning to 2023 soon becuase i thought that would mean we would get at least a full episode of when they're thrown back into their new timeline. But alas, we got maybe 20 minutes where they rushed going through how the world looks now. What I think could have made this new timeline so much more impactful is if they showed a little memory flash of Eun Gyeol's new memories from this new timeline so he knew what had changed.

The ending was just very open and I would have preferred for it to have come together more clearly.

That being said, this was amazing. The characters, their struggles, their relationships... It was so special and I cried a lot in the last ep. And because of that, I can't not give it a 10/10.
