But one day, she finds herself forced to take in her younger relative, Ko, at her apartment. Still resembling how she remembers him from ten years ago, Ko has grown into a classic heartthrob with an overwhelmingly handsome face. Rika unwittingly lets her guard down in the face of his charming demeanor, but this guy with the perfect looks has a shocking secret! "All I want is to admire my anime boys in peace," she insists. A dangerously close living arrangement with a younger, scummy wolf in sheep's clothing begins!.
