Ah yes then we speak in objectively!
They broke the old cliche and start putting random characters at episode 1, then they progress the story quite smoothly with giving each character an arc for their own.
Does that not sound like a better harem romcom anime?
(oh and the alien,mahou shoujo, etc. at one room thingy just pointing out the originality. Never seen an anime like that. Correct me if I'm wrong)
