A drama that is mainly based on dilemmas and questions about how people see me with my disability.
Sakura who loses his hearing begins to distance himself from everyone including friends and family.
You see his pain in the series, his difficulty with the lack of hearing.
Throughout the series he understands things and connects what is happening to him with the present.
Oba on the other hand after Sakura dumps her she starts dating his best friend and is basically unaware that she still has feelings for Sakura.
She is learning sign language "to communicate with him better".
And little by little memories from the past are coming back.
Sakura's best friend - all the time with the fear that Sakura will return and Oba will leave him.
He is ahead of his time and breaks up with Ova with the excuse that he didn't think about his own life and desires and always did what she wanted to make Ova happy.

A touching and moving series in everything related to Sakura and his dealings with deafness, but - the drama is a bit smeared, and every second there are different aspects of farewell.
The last chapter was definitely the most beautiful. I just *hope* that the whispers in the ear were the sentence-
"I love you".
