It's two in the morning and I just finished this drama.
I have the tendency to binge watch stuff because I quickly lose interest, not all the time but most of the time.
With this, I watched one or two episodes a day. I took my time and I had fun watching it.
It's slow and the big mystery is stretched out till the last episode so if you expect fast paced thriller mystery you are at the wrong place. It's more about characters and healing.

Story
I started watching this because of Kimura Takuya and because I love stories that involve memories.
Technically we are a bunch of memories, if we lose them, who are we?
Do you stay the same person or do you change? This drama touched on these topics and I liked different opinions characters had. The adults wanted to forget the past while the kid wanted to remember every moment.
And Yukio was scared, he was scared of his past and who he was.
He lived three years as Yukio, if the memories come back what will happen to Yukio? Will he disappear?

Things I liked
- Episodic format. Every episode had a different story, different thing he had to deliver while the memory plot was sprinkled in between till the end.
- Yukio's past.
- No romance, just friendship.
- The relationship between Naomi and Yukio, she took him in and protected him.
- The way Yukio unintentionally helped people while delivering stuff.
- Yukio being done with half of the characters. *The eye roll*
- Badass women Naomi, Sakuhara and Shika.
- Yukio's hair, I had to mention it because it feels like his hair is also a main character.
- The catchy song in the opening of every episode.

Overall, it's worth watching and I would recommend it to people who like character driven stories. It's original and sometimes weird but I liked it.
