In Tokyo, lonely patrons pay to sleep ("soine") with someone. Massage, cuddle, sleep… for comfort and nothing more than the warm embrace of another. Tasuku, a young man fresh out of a relationship, starts a new job as one of the cuddlers. He's nervous and reticent, but soon finds himself with a procession of clients, male as well as female.
