I think this is one of the best anime i have watched till now as sometime the witty way the character back story was conveyed is one of the examples, it's deep but not everyone can get that.
I like to watched the anime which MCs are not mess and loud so this is the enjoyable anime for me, some of the characters could get more screen time.
The nature of the anime is good and can sometimes relate to the viewers. If you are looking for the Slice of life genre, you should give it a go. I like the way the anime is presented. Although the ending is a bit rushed, the rest of the anime is enjoyable.
