My title sets it up. This is, as many have mentioned, a "typical romantic comedy manga." In other words, it's trying to pull off every cliche in the book, from the harem triangles to the shoujo melodrama.
But for its good points... it's funny. That's about it. The art is nice as well. Truly, I couldn't imagine anyone reading this manga because of the awesome romantic plot. The draws to this manga are its "readibility" and humor.
With the good points summed up, I'll give the premise of the characters. The male lead doesn't seem to have much of a personality, as it is for most event-driven mangas (which this most definitely is). The female lead, in direct opposition, has a ridiculously exaggerated tsundere personality which may grow on you. The side/main female love interest, Onedera... she's just the "normal, shy girl," who is fairly capable of getting on people's nerves without the excuse of being a tsundere. The other side characters are actually funny though, and balance the... negative aspects of the main characters.
Basically, the characters mean absolutely nothing, except for maybe Kirisaki, the main female. Her personality is actually strong enough to influence the plot, whereas the others are just... blank slates that let things happen. So overall, this manga is about having ridiculous (cliche) things happen and the exaggerated and the admittedly funny things that result from them.
I personally read it when I have time to burn.
