Tojikomechattemo Iinda yo?

Kenji lives alone in his apartment and never goes outside. His only joy is meeting Julio, the guy from the delivery supermarket. Julio has a cute face, and he's always kind and upbeat, so Kenji fantasizes in private. But, one day, when Julio comes over after hours to rectify his delivery mistake, Kenji makes an "indecent proposal" in the heat of the moment. Love, life, it's all over... or so Kenji thought, until Julio agrees with anticipation. Not only that—Julio then calls Kenji "master," and sweetly indulges his secret desires! A stay-at-home depressive meets a bright and chipper boy.
