The story will get you hooked because of the interisting concept and the emotions and the personalities of the characters is so surreal. Opening Song is very nice got hooked by it.
Overall the anime was wonderful. It has that nostalgia of you wanting to go back to high school or change something you did in the past. It will make you think of the regrets you might have done in the past as well as your successes. It is very rekatable cause I think we have that feeling that we want to go back and change something or to experience something again.
10 out of 10 for my taste.
