The drama focuses on the experience of a college student Kohei, who is hard of hearing and his classmate Taichi. While the plot may not be ground-breaking, it somehow excels in character development. It also respectfully handled the topic of disability.

The heart of this drama for me lies in the individual development of Kohei and Taichi after meeting each other.
It sensitively portrays Kohei's struggle due to hearing impairment and how this impacts his interactions with others and his sense of self. I liked how he socialized and made friends, finally coming out of his shell after meeting Taichi. It was absolutely a delight to see him smile.
Taichi, whom I would call a sunflower in human form is one the most precious characters I have seen on-screen. His vibrant and compassionate nature breaks through Kohei's defences and yet somehow managed to find his own path and a sense of purpose in life. Although he needed some lessons in self-worth along the way, he managed to make it through. I enjoyed his interactions with his two friends and the way they both were supportive of his decisions without undermining him.

The dynamics between him and Kohei were portrayed with nuance and authenticity. Their relationship/friendship evolves organically. Taichi doesn't only sympathise and support Kohei but also challenges him in certain ways that encourage personal growth. On the other hand, the way Kohei slowly learns to trust and engage with Taichi reflected a touching journey of self-acceptance.
The way those two interacted - whether laughing, having deep conversations or sitting quietly beside each other for support felt so genuine and unforced.

What (sort of) disappointed me was the last episode or how they handled the 'love' in the love story. As a slice-of-life drama, this was 10/10 for me, but the confession from Taichi felt completely unrealistic and rushed considering how obtuse and oblivious he had been to Kohei's feelings and his own. Seemed pretty out of character.
Another character who felt completely unnecessary was Maya. Her heart might be in the right place, but she still needs to learn about respecting boundaries and some manners. I do acknowledge her struggles, her care and protectiveness towards Kohei but I feel almost all the time her character was saying things which were/are uncalled for! I was hoping she would be a positive catalyst in the story but to my surprise, I don't think she contributed anything substantial other than some jealousy here and there. 

Overall, it is a compelling watch if you consider it as more of a slice-of-life narrative rather than a love story where empathy and understanding are the driving force.
