This anime is an ecchi harem. This is what it is and that is why you should watch it. This harem does ecchi harem is the way that ecchi harem is supposed to be done. It puts a main character who has features about him that are like able but not to the extent that every girl he looks at would fall for him and then has every girl he looks at fall for him.
This genre works like any feel good genre. It simply presents you with what you want to see. The thing is what we want to see isn`t always hentai. Now a lot of people might be asking why wasn`t this anime just a hentai. Well why does everything ecchi have to be a hentai. There`s enough hentai I think this anime is fine for what it is. It`s a perverted anime but few people don`t feel good when watching a harem or a romance that is reasonably paced. This is just kinda a romance that skips over the boring stuff. That is not necessarily better than a romance since the boring stuff is character development which makes the pay off better but sometimes you just don't want that. Sometimes you want to turn your brain off. Its like the gurren lagan of romance. Also it's rare that you find a ecchi harem that actually has a somewhat decent message in the sense of don't judge a book by its cover (although the payoff for following this might be somewhat out of proportion). But ya all in all it was a solid ecchi harem. Nothing revolutionary but serviceable and among the slogs of nisekoi and jitsu wa watashi this is a nice breath of fresh air
