On a whim, Shina decides to paint his nails with his sister's nail polish. Seeing the beautiful sky-blue color on his nails makes his heart pound, but he's worried that it's weird how into his sister's stuff he is... so, he confides in his classmate, Shibuya. After talking to Shina, Shibuya developed an interest in cross-dressing videos. Confused by their feelings, the two boys find themselves painted in sky-blue confusion in a rose-colored romance.
