I really loved this series.

Is it sweet? Yes
Is it wholesome? Absolutely

The story is not that long and that's good, it can start getting stale after a while as the story doesn't really progress a lot of the time. Nonetheless, it is really wholesome and gives you heartaches through and through.

The art is amazing and I loved the feeling and theme. The weak point though would be the characters as they are fine as they are but could have been a bit more fleshed out. Which gives them -3 in that department. But then again, looking at the lenght of the manga. It's hard to flesh them out and work with it in just 22 rather short chapters(+1 for context).

Overall, I think it's a really wholesome manga that a fast and enjoyable read. If you like wholesome things definetly read it. If you are more intreseted in character development, maybe not.
