도치 문장에 대해 잘 아시는 선생님께서 아래의 문장처럼 고치는 게 맞는지 알려주시면 감사하겠습니다.

not only does he sing, but he also plays the piano.
not only did i fall in love with the dector ,but i was also fascinated by his service.
처럼 도치된 문장을
원래의 문장으로 고치면

he not only sings, but he also plays the piano.
i not only fell in love with the dector ,but i was also fascinated by his service.
처럼 되는 게 맞는지요.
