This seems like a tough topic, and I personally wouldn't count Always. Even his "physical problems" aren't until the end. The closest thing to sensory might be him not talking, but even then, him not talking isn't losing one of his senses.
Yeah, the only ones I could maybe think of were already said or used as the example. I could probably mention one with a very minor side couple (so not the leads), but even by the end, it was kind of ambiguous if they became a couple or not.
