What I like:
The OST, it is upbeat and I could listen into it almost everyday.
Visuals are very polished, too polished.
Slice of life take on each episode.

What I dislike:
It is a mediocre slice of life story. There was a weakness in its story telling.
And with that mediocrity, the series suffered from the theme it ought to deliver and just became a fan service. Character development felt rushed making it feel inorganic.
Also, the ending felt rushed too.

But overall, this is a watchable series where you can gush on the 'trinity' and just don't care about the plot and what will happen. You can even watched an episode as a stand alone and you will not be lost.
