Everything makes sense except the need for a twist. If Ruby's dad is her dad, but doesn't know he is her dad and he raises Ruby as if she were one of his daughters (which she is), why would there need to be a twist in the first place? Why can't their father just take care of them like a normal dad instead of having this big complicated plot point.

Not to mention anyone that is good at math would have figured out he is the father. especially him. If he did become legal guardian (first off he would have been notified that he was her guardian), there are tons of steps that need to be taken first. But once he got a copy of her birth certificate and counted the number of months after the reunion, it would be pretty apparent to him that he was the father. He would most likely have to hide the fact from his gf/wife. He would also have to explain to her why he is the guardian, considering people don't just make other people guardians of their children for no reason. It just seems like a lot of things in your version don't need to happen to get the same result.
