The weight of words and actions in this show is amazing. Not just in spoken word but every time they're using sign language, the character puts the entire weight on it. It is so comforting yet so heartwrenching at the same time. The cast and the performance is exquisite, to the point I'm just riding along with the characters and not thinking "Oh, the actors are amazing!"

Ha Yi Chan as a character has so much depth, both as the adult and the teenager. Him learning sign language just to be able to communicate with Chung Ah, out of curiosity and kindness. And then being able to watch the exact moment he falls for her like Ha Eun Gyeol narrates is honestly a feel good moment. The way his character grows to hear Chung Ah through her own words is amazing.

Chung Ah as a character is done PROPER justice by the actress [I forget name, my bad.] The expressions, the weight her actions carry and the story she has all on her own ties the entire thing together. I haven't been so taken by a character in a long time.

Ryeoun as Ha Eun Gyeol and Seol In Ah as Choi Se Kyung ground the show as the time slipping characters. the great part about these characters is their individual motive.

Each character has motive or rather grow into their own. It's a really refreshing portrayal of a teenage drama, even if it's in a cliché plot tree. The story carries enough heart to make the characters absolutely steal the show.

It's a MUST WATCH!
