This manga is seinen, but mostly reads like a cute, innocent shoujo, save for the large breasted rival, and the occasional mention of porn.
I'd say it's kind of an average manga of its type. The concept isn't inherently funny, unlike the really good 4 koma manga I've read like Tomo-chan is a Girl or Monthly Girl's Nozaki-kun, and the jokes aren't really the laugh out loud type, and therefore its appeal rests solely on its characters, which at least feel unique rather than bland as is often the case in romance manga. In all, I'd say the manga is cute, but never pushes itself to really shine. However, the art is pretty stand-out for a manga of this type. There was never any questionable anatomy, and everything is very cleanly and confidently rendered.
