Ended reading on ch6. Read ch 7 onwards
Kaede (a rabbit) is set to an arranged marriage with Ren (a wolf) to help his tribe upon the chief's request. Because of Ren's emotionless face and curtness, he ends up bickering with him a lot. Ren turns into a wolf due to a surge of emotions and Kaede makes him his mate to turn him back to his human self.
