Raw acting, raw feelings, raw music. Everything feels so real and so raw. Impeccable directing. This series left me empty afterwards and kept me thinking about my own relationship and life because it felt so incredibly real. I'm sure many other people will also experience this since the subject is something many of us experience or can relate to.
Parsa Pirouzfar was the perfect candidate for this role with the feeling he put into it, Hoda Zeinolabedin delivered the perfect counterpart and the kid did an outstanding job. Every role was done perfectly and the right people were chosen.
The only flaw I can think of is the amount of episodes which aren't many, but maybe that worked in it's favour and kept it so interesting.
