I did not like the series, most people say that this series is innovative ... but I say, in what innovates? same composition of characters in any romantic novel (the 2 tsundere protagonists who like each other, but none dares to take a step to the point that it becomes annoying, secondary characters whose only function is to look silly on screens to make people laugh no deeper development).
In my opinion until the anime of ueno-san is better than this since at least does not have the typical composition among its characters.
In short, I do not see that people see this anime when there are much better romantic comedies.
Both psychological game to make the other do something that the 2 want to do and has me sick.
