First time writing a review for a series! The reason for writing this is to make people aware of what they are missing! Maybe some don't like it but still I want to suggest that 'watch the original version first!
I was not gonna watch this although I love Korean dramas.. but one day I was scrolling reels and I saw a reel on a clip from japanese series where they were doing sign language and it attracts me to the series.. I find out it's name... although I didn't like japanese series that much but I still decided to watch this one! That series was the original version of Korean series "tell me that you love me" original named as "Aishiteiru to Ittekure" .. at first I liked it but after watching whole series it was ok for me !! Than I decided to watch its Korean version coz I wanted to know that how much good job they have done it to make their own version! And frankly speaking I didn't liked the main couple at first but then I decided to judge them after watching the series and I was not wrong!!!
They did change the story about 30 percent...
But the fact that this version is boring for me! Not attractive enough to binge watch it!!!
I am writing this review after watching 7 episodes and there is no chemistry between the main lead.. it feels like a forced relation! Like they just have to develop a bond but it doesn't click like a good acting!!
The sign language is the main thing and it lacks that also.. the FL is so bad at sign language .. she didn't learn it properly comparing to the japanese version !
The japanese FL looked like the desperate one who learned sign language for him..
but in Korean version it felt like it was just a job for some particular time that she needs to do and that's it!!!!!! I really felt bad for every bit part coz I loved the japanese version!
I realized the true worth of original story after watching the remake!
Also the ML in original story is more jolly person than in the remake one!!!
Personally the couple was lacking so much of everything! Especially chemistry! I didn't felt a thing!
Speaking of chemistry the Japanese couple was really good coz I felt something from their first interaction and gradually it grows!
But in Korean version , from their first interaction to till now they are just 'a stranger who knows a little bit about each other' for me! I felt that the main lead is carrying an invisible protection layer around him and don't even allows the FL to cross that and the FL is also not doing much of a job going beyond the limits!
Talking about the sign language , the main leads of japanese really did a great job in doing it so smoothly !! They were so smooth that it didn't felt awkward and wierd watching them ..
I was impressed by their sign language!! And the way they express themselves while doing sign language . Maintaining facial expressions and all that ..
On the other hand I felt that Korean main leads were not that good! ML was better but not so good like japanese version ML. . maybe you felt it exaggerated but that's how I feel after watching both versions!! Because conveying your message in sign language with proper facial expressions and body language is a big deal ! And they done it nicely like a pro. While the Korean version lacked that thing !

After reading reviews , I personally think that people are finding it good coz they haven't watched the original version.. that is so good compared to this one!
I am not good at writing reviews but writing this one coz I find it so wrong for the original series!!!
Hope my review will be helpful!!!
