Lark, who was born into a poor family, suffered separation from his parents when they were framed and murdered by the scheming government officials trying to survive and swearing revenge he becomes a thief (and a murderer). But the destination seems far when he suddenly gets killed and then reincarnates in the body of a rabbit. Trapped and force-fed carrots by an unexpected love interest, will he be able to get accustomed to his new life, and can he exact his revenge on the corrupt government and the empire that oversees it all without getting fat?
