It's not the type of story that you would make in 'shorts'. A tsundere guy needs a further development for it to be appreciated, plus the relationship they have is actually unhealthy and insensitive. It tries hard to be funny and make a comedy out of their skits, but if you think of it, the guy is actually irresponsible with what he has, given that her girlfriend is so, so much understanding on behalf of him.
The art is very good though. It follows the art style of good anime shows that I've watched. Too bad, the story didn't match it.
