The Kawai Complex Guide to Manors and Hostel Behavior

The Kawai Complex Guide to Manors and Hostel Behavior is also listed as Bokura wa Minna Kawaisou on some trackers — same show, different title convention. It's a TV series across 12 episodes out of Brain's Base. It's finished airing, so the whole thing is watchable start to finish.

On the shelf it sits under Comedy, Romance, and Slice of Life — worth knowing if you're comparing comedy anime specifically. If The Kawai Complex Guide to Manors and Hostel Behavior works for you, HAIKYU!! and Rascal Does Not Dream of Bunny Girl Senpai are close matches — see the full related list below.
