Personally speaking it's my favourite anime till now ya I know i have not watched that many anime. But this anime is a worth watch. The soundtracks are really super awesome. It's quite suprising to produced such a variety of songs for just 13 episode series. Other ost are awesoem too fits best.
The character development of the protagonist is literally admirable. Every character is introduced well and love each one.
At first it feels like a normal anime but man the emotional value is quite attaching and leaving a eternal impact.
I recommend everyone to atleast give it try.
