Fruits Basket: Tohru's Cousin and Kyo's Brother

What if Tohru had two more cousins and Kyo had a younger brother who was the dog of the the zodiac? Their lives are turning around when two of them decided to leave their family and lived a life of a lone wolf.
And also, I would like to tell the story of Fruits Basket from the perspective of a fan-fic character, but also adding some parts for the lives of the fan-fic characters.
Masayuki Honda is a 17-year-old Filipino biracial living in Japan and the maternal cousin of Tohru Honda who was supportive of her. Handa Sohma is the younger brother of Kyo Sohma and the dog of the zodiac who was his supporter. They both have something in common: They are sympathetic of their sufferings.
Will they escape such suffering of theirs and even their own?
