I like the fact that no men has eyes. Means that these are only but depictions of men, purely for the fantasies that she has, also here men seem to be a bit simplistic... the girl characters are okay but it really lacks character in all of men here.
Just looked at the raws and at ch 124 there is a tiny fraction of Ai-chan x Onii-san interaction there for god knows how long of a completely absence of onii-san. So Ai-chan and Onii-san are still canon.
