This is a reverse harem ending.
The FL sleeps with her brothers and their father, and would continue to do so. The only reason the ML is the father is because she *loves* him.
Also, is this incest or not? Depends on how you define it.
The brothers get hard for their sister whenever they touch her, while NOT knowing that they are in fact not siblings.
That is incest for me.
And, literally out of nowhere she develop those *romantic* feelings for the ML, after learning that they are in fact not a father-daughter pair.
