Your kindof forcing the blend to match/meet at an unnatural location which yeilds the "gotta twist up to do that" result.

If you change your method slightly, you can get a good blend.

So the hole you cut in the fuselage could be more of a natural result edge. I untrimmed the hole (old red) to recover the surface, then I extracted the lower edge of the wing (red) and ran offset on it to meet the old holes edge (blue). I used the new shape to trim the fuselage and then could get a good blend with the wing.
