Remember I don't read the light novels. For Aesthetica, I was referring to the anime. My memory might be bad. It didn't really felt much of a harem to me, personally. It was more about Miu and the girls didn't really express a lot of romantic interests in him. Akatsuki seems to only neutral with the other girls and caring for Miu more than the rest. I haven't seen Shuffle yet.
Oh yeah, I did forget about those harem shows. They also probably stretch it out. I guess there is the other half chooses while the other half stalls or don't choose at all.
