Ok I'll admit it, I was quick to judge. I didn't like the first episode because it felt like it was going to be a super heavy lolicon because of emphasis on Popura's shortness and Takanashi's love of well...children. I meandered through the first couple episodes, all grumbles and eye rolls.
Somewhere around episode 3 or 4 I started enjoying things, as other characters got involved, like Takanashi's family, which is great, and Inami in general, who I think is a great character. By episode 8, I was fully invested and loving it, forgetting all of my initial worries.
All in all I thought it was a good slice of life in the end, not earth-shattering, but fun to pass the time, with enough characters that you'll find at least one to like. A good filler show for chill summers.
