Shishunki to Danshikou!? to Nakano-kun

The other characters exclusively exist in their relationship to Nakano. Despite supposedly being a friend group, they never interact with each other unless it somehow relates back to Nakano. Even that might be fine if the author was willing to do something with Nakano and the girls, but it's the same joke every time. The girl does something girly, then Nakano goes "OMG boys are cute let me clear my mind". Wash, rinse, repeat. There is no development. We will never know why the girls are at an all-boys school, or see an actual relationship blossom. Very disappointing.
