This is a Review on the Anime not the Manga
I'm going to start off by saying I liked this anime because of its lightheartedness and would give it a 7 out of 10. Though the anime did have its problems, since some of the main characters are in primary school they're going to act like children, including childish behavior, antics and ect. There also was many times that the characters themselves didn't make sense and things occurred that wouldn't happen in real life but what anime doesn't do that?.
For the romance part of this anime it did a good job of making you want their relationship to work out despite their age gap. The anime also has a great humor about it.
So all in all this anime had its downfalls and upsides but both these things together make this anime lighthearted and comedic. I would not recommend this anime for someone looking for a serious anime or a nail biting romance though it is still one worth checking out.
