Another "pornhwa" as many online reader comment stated.

Comment: this story makes no sense, if you're going to make a boarding house with some spiritual force that makes people horny why would you continue to establish your boarding house business there? It would've made more sense if it were a play house or brothel. Ah the imagination of korean artists are similar to a 12 year old just like SAO....
My comment Here: I'm not sure if the MC lucky or unlucky but at least our MC not full pervert (hentai). Here how it go; on one hand on normal situation it look like a normal Manhwa while on the other hand when the female get horny by the supernatural force of the boarding house you get vanilla (in hentai genre term) with a few "Comedy" add to it. Our MC just in weird situation; He either being force or drag into sex by "female in heat" as one can say by the supernatural force most of the time with a few exception on a few time where he take the lead. Our MC is somewhat of a "herbivore" and most of the female that live in the boarding house are around his age or older (mostly older). This is like an alternate version of "Love Hina" with an adult theme in mind
