There are a lot of cute girls, sure, but how is this a Harem show when only 2 of them have positive feelings toward him, 1 actual Love and the other very ambiguous friendship that might evolve into more?
Unlike your traditional harem, he also came out rather brutally to the one who professed her love to him, to tell her he actualy love the other one (Which I found to be awful mature of him, instead of leading her on as a "fallback").
I'm only at ep 18, but so far I see the show mostly as a decent exercise in trying to have Otakus have an in-depth good look at themselves:
- If they were propelled into a Fantasy world, not only would they be deemed useless, they would probably die horribly when trying to get involved
- Others have feelings that do not revolve around them. With an average Neet/ Otaku attitude, people are likely to either be dismissive, cruel, or even outright dislike/ hate you for your lack of social ability (and the MC is actually rather good at pretending, with children in particular)
- Others do not owe you anything, and for people to like or admire you, you will have to show selflessness or actual concern for others than yourself.
- For people to respect you, you have to show skills or strength of character relevant to your context, and lying or faking it will only bring you so far before making things worse. And the higher the stakes, the worse it will be.
- Having certain feelings toward someone else do not mean that said feelings will be reciprocated. But it doesn't mean they won't. You have to be honest and take risks, for maybe someday see a positive outcome.
- Self pity and being pathetic, hating yourself, might get you some help from people who will feel bad for you. But it will not get you respect, friendship or love.
edit: finished it last night, and I can honestly say I loved the show. The character growth is a bit quick, but after what he's been through, it's a welcome change that he decides to use his "gift" as such instead of whining about his curse.
Looking forward to a 2nd season (will probably be a while I read, as they have adapted LN's 1-3 out of 4 published, even if there is more material than that with the Web Novel).
