This is one of good underrated series
The anime adaption aired back then but the feedback was really low. Especially in its season.
I make the review about this in MAL, despite the art is not amazing. It is really heart-warming and flows well.
I hesitate at first if it's turned out to be shounen-ai. Fortunately no. This is unexpectedly deep and the situation is quite complex. It shows how lively the athmosphere is, cute and calming. But when a certain topic was brought up, it touched my heart.
It really is good. I recommended it.
