Double Standard

Riku, despite being heavily pierced and working at a brothel, is surprisingly innocent and gullible. He comes into the clinic Keigo works at accompanying an escort, after which Keigo never expects to see him again. When he finds Riku drunk and barely conscious outside of his apartment, however, he has no choice but to bring Riku in and take care of him. Turns out, the two are next-door neighbors. Even though Keigo feels this guy is nothing but trouble, he finds Riku's naivete adorable. The two become entangled and fall more deeply in love than they ever expected.
