If Naoki Irie had a smart and beautiful cousin, how would the story happen? If that cousin lived in the Jiang family earlier than Kotoko Aihara, would Irie's mother still like Kotoko Aihara so much? The ending is unknown.
The cool, handsome and smart Irie Naoki vs the cousin who is smart, arrogant and cute, but occasionally a nymphomaniac, who is better?
Hee hee, it seems like cousins can get married in Japan. Please forgive me for my obscene love of incest.
