If you're referring to loving two specific people or things:
* "Eu amo os dois" - This translates to "I love both of them" and is the most natural way to say "I love two" in this context.
If you're referring to loving the number two:
* "Eu amo o número dois" - This literally means "I love the number two."
* "Eu adoro o número dois" - This is another way to say "I love the number two," but with a slightly stronger emphasis on liking it.
Important Note: The Portuguese language doesn't have a direct translation for "I love two" that specifically means loving the abstract concept of "two."
