For a while I really didn't like this manga, but going back to it now, I get it a little more. These two are just odd people! Yeah Sou kinda ticked me off too but then I realized that Haru's not really any better. They've both got a touch of petty and dramatic. And both need to work on their communication skills. I'm still not 100% in love with this manga, but I like it better than I did the first time.
I'm sorry but that plot was waaaaay to abrupt! Two pages in and boom! Within one page he's back to the human world and then within five he's back. Maybe this is just because I read the fifth chapter all on its own, but I still think my head'd be spinning.
