I loved series 1, It was cute and quirky, and I have been waiting excitedly to see their relationship develop and grow.
Sadly series 2 is more or less a repeat of S1, but way worse. There is zero development and growth and absolutely no chemistry between the main characters.

Considering Minato and Shin have now been together for 3 months, they appear to be in exactly the same place that we left them at the end of series 1. Minato has a hissy fit every time Shin gets any where near him, and runs away screaming, while Shin stands about looking like a wooden plank. Shin isn't even allowed to use Minato's first name!

The whole series goes on like this for every episode until it becomes extremely annoying and boring.
Later there is a horribly contrived "accident" that is utterly pointless and adds nothing to the story. It is lazy writing and I have to wonder if even the script writer was bored by this point!
Overall a disappointing story I blame the script writer and the director.
