This anime is a great watch, for me it brought up a lot of feels from first love and how it affects your life to preparation for exams and graduation.
Art is great and tends to improve towards the last episodes. Character design is also great and characters act naturally when faced with different life choices .
However where the story lacks, is the time frame chosen for it. Had it been chosen at the end of hischool with graduation and university admission, it would have been more believable. Also it's a story of first love however it should have stopped before the end credits scene. The end credits scene should not have been added there, it makes the story less believable. Apart from this, it would have been a 10 in my book, factoring the above it's a 9.
Definitely recommended to watch for the feels depicted, you will definitely find a piece of yourself in this anime.
