I only read volume 1, but I don't recommend this series. First, the storyline is confusing since the story doesn't explain why the main character (Kureha) has nightmares about bears and Ginko. And the story doesn't explain why everyone is a bear. The story stated that all humans except Kureha are secretly bears, but they're just unaware of them. And they say the birds, cats, pets, and other stuff are bears too, but they didn't explain why either. Cats aren't bears, they're cats. Birds aren't bears, they're birds. And people aren't bears either. But the story doesn't explain why everyone's secretly a bear. And thestory doesn't really develop the characters since all of them are Mary Sues or Gary Stus. And the author shows the characters' underwear, butt, groin area, and the naked shower scenes way too much. They also show the three girls in showers, who are shirtless. I'll assume the author wants to show shirtless girls with exposed boobs. And that's quite bad. And the author seems to want to let people peek under skirts to see girls' underwear. Which is bad too. And some of the logic of the story doesn't make sense either. Like the backstories of various characters. And the story is quite disappointing, since it's just a bland story without much development in the plot and characters.
