Any plaintext input with the correct OTP could result in the ciphertext you have. For example, suppose you have ciphertext:
45 F1 C3 29
The plaintext could be LOVE (or Love or love) with the right OTP. It could also be HATE (or Hate or hate). Or it could be any other four letter word. Or a three letter word with a space or a period. You get the idea.
