In moves Gabriel (the blonde of the title), Juan’s stoic and very handsome co-worker, who is recently widowed and struggling to support his young daughter. Shy and reserved, Gabo is reluctant to follow Juan’s wandering hands and meaningful looks. With a revolving door of beauties streaming out of Juan’s bedroom, his machismo seems firmly in place. However, the attraction between the two men is undeniable. What starts out as a sexual relationship based on convenience of location, soon develops into the engrossing evolution of a tender and intimate relationship, which is as sweet as it is heartbreaking.
