No, I mean exactly "replacement" of the sister with a new heroine, while the previous one became a couple with the main character.
I noticed that in some Brother–Sister Incest plots MC "gets" a normal sister, after the main heroine turned out to be a non related sibling and became a couple with the MC. For example, a hero marries an adopted sister, after which it turns out that he has a native younger sister. If any trope, which is based on this, or similar to this?
