I have binged watched the whole series more than 7 times and let me tell you, I always feel same the way I felt when I watched it first time.
The story, the characters everything just fits perfectly like puzzle pieces in place.
Aoki's character is like a 10 year old. Trying to figure out his feelings and being courages enough to face it. Whereas Ida is guy who wasn't a social person but was taken aback by the situation. The story revolves perfectly around on how Aoki and Ida's relationship changes and how they evolve.
Short series with the perfect amount of episodes just made to feel like a cup of hot chocolate in winters.
