One of the once-in-a-life time anime.
Especially when you get older, emotions tend to get weaker, and don't move you as much as during your youth years.
This anime makes you uncover the lid to many hidden feelings and make them clear.
Sweet scenes, incredible artwork, pure and unintended humour and jokes, and well-thought/well-designed characters with unique personalities- not the typical pattern you see in today's anime.
Soundtracks: music that fits to each scene, music that helps to describe the emotions of the moment.
I personally love Flumpool, because of the bittersweetness of their songs, that fit perfectly to the story. The ending is an old song, which I found " playful " - it reminded me of my childhood, when music was purer and unique.
I hope you enjoy this anime as much as I do, and appreciate all emotions inside you - there is no negative or positive feeling. There are colourful feelings that have no name - and we have to learn to embrace them all.
