No, this show is not as good for me to call it a miracle. It's a very nice romantic comedy with drama and anything that you'd expect from a typical coming of age anime.
What really flashed me here was the Russian language. You see, I grew up with either Russian movies or American movies where Russian is totally butchered and made fun of. Also, I know that the Japanese like other languages like English or German, but due to their very specific use of the Japanese language, they rarely pronounce anything correctly.
Imagine my surprise and joy when I heard real Russian in this anime! Sure, it's with a heavy accent and the main characters have a better pronunciation than the side characters, but still. There were longer parts where I did not even need to read the subtitles and I understood everything. Kudos to the voice actors!
It was worth it to hire a Belorussian teacher of the Russian language as an advisor. Everyone has done a great job and I am looking forward to the second season.
