Bookworm Kazuhito Harumi dies attempting to stop a robber in a cafe, then wakes up reincarnated as a long-haired dachshund. His new owner turns out to be Kirihime Natsuno, the woman he tried to save and, unluckily for him, both a sadist with a fondness for scissors and his favorite novelist. Unable to speak but somehow understood by her alone, Kazuhito settles into dog life while nudging Kirihime toward finishing her overdue next book. This manga adapts the original light novel series.
