The Rose (2003)

Female lead is the same actress

The girl gets adopted into an abusive family, something like a Cinderella story, except that the Rose is a bit more freaky.

Both have incest/taboo relationship.

90 Days of Love the main leads are cousins; while the Rose, there is half-siblings.

Both are very melodramatic, and I personally like The Rose better, but both are good for what they are.

A stepbrother and stepsister fall in love even though they are not blood related, their love is still forbidden.

Both dramas involve incest (supposed in one, real in the other).

"Newlyweds" Keiichi and Akira Hirose have moved to a new city. Keiichi, who works as an author, and Akira, who works with kindergartners, are hiding a big secret from the people around them.
