I would say this isnt a typical Kdrama its clear that its netflix made. But the acting and story are so great I didnt really notice.
I would recommend this to non Kdrama fans as it is just a great show.

As always Le Je Hoon is amazing, he is like a chameleon in all of his roles, completely nailed this character.
Unlike the garbage fire which is 'It's Okay not to be Okay' the portrayal of Aspergers here is handled with sensitivity, allowing the character to have depth and be more than just someone with Aspergers.
Even though each episode usually handles a death it doesnt feel melodramatic, it is interesting and touching. There are many bittersweet moments but there are also a lot of funny and lighthearted moments.

Basically a great show!
