Yukino Yukinoshita was not a boy, after all!
Therefore, even if the two sisters had been given the same conditions—even if Yukino Yukinoshita had been somewhat more outstanding than her older sister—the Yukinoshita Family would still have been handed over to Yukinoshita Haruno, so long as the gap between them was not worlds apart.
