Finally she excises an hour of study time to spend on being able to look at him without intervening furniture or flinching. She finds it's possible to do this in her mindscape, without having to use a notebook. She can zoom in deep into a rose petal, find a level of detail beyond which there are no patterns, and write, directly there. This isn't an ideal memory aid - if she looks later the words aren't exactly the same - but it's much faster for sheer processing, and the chosen modifications morph into the structure of the rose without special effort as soon as she's sure she wants them.
She behaves with more equanimity about his nudity after that. "You can stop trying to remember to hide behind things," she tells him.
Time passes. Belle continues her magical studies. The Beast continues to read when he can and snuggle when he can't.
A few days after Belle makes herself comfortable with his true form, a storm blows up and soaks the gardens with driving rain. The Beast, of course, dashes out almost immediately to play in it.
In less than an hour, he's back inside, soaking wet and slightly muddy, with twigs and brambles tangled in his mane. If she looks, she will find him on the kitchen floor, trying and failing to brush out his fur and laughing all the while.
"...Even if the curse becomes permanent, that just means there are ongoing effects that aren't directly disenchantable. Maybe I should keep some of the magic books and the dictionaries for the foreign languages under a shelter of some kind, out in the forest, so I can take them with me and keep studying if we hit the time limit and it sends me away, and then maybe I could do something. I'm not at all optimistic - but it might be that if I learned enough, I could - I don't know. The thing that seems most likely that I could one day be able to do in spite of all the supposed obstacles is kill you. I don't even know if I could do that. I don't know if you'd want me to."
"If the time limit comes due," Belle says, "and we're still stuck here then, I'll leave with all the books I can carry and drag, and I will work on it, and I'll try to anti-curse you where I couldn't un-curse you, and if that doesn't work I'll see if I can get you out of here - the other way. But let's hope it doesn't come to that."
"Sadistic nut of a witch," mutters Belle, "who would take all this power to change the world and do nothing productive, not even pointless harmless whimsy, but - disproportionate absurd cruelty, out of all scale - when did that start to seem to her like a worthwhile use of pain and power -"
She studies.
She's really not making much progress in her curriculum. If she's going to have any prayer of disenchanting the place before the deadline, she's going to have to narrow her focus. She can't just study disenchantment - she has to be specific, cross from her starting point to her destination on a tightrope instead of insisting on building a whole bridge. She can fix the breadth of her knowledge later. Right now she has something very particular to get at.
She goes to have another look at the curse fondement.
Well, Belle can talk to him about that later, she doesn't want to have to cast the spell to let her see the details a second time. She takes careful notes, on everything, including the stream of violet. Does it look strong enough to carry his half of the disenchantment? The curse is designed to be broken by love; maybe it would be possible to subvert it with half the recommended dose and some more magical work...
There are no books that talk about how to accomplish the kind of delicate surgery that would be needed to change the structure of the curse in the relevant way.
Well. She has many notes about the curse. She shaves off everything she can from the curriculum she's designed - disenchantments relating to anything not powered by Heart, disenchantments that are aimed at short-term curses, disenchantments that simply hasten programmed timed expiration.
She cuts down her estimate by about four weeks. This is not nothing, but it is not enough to be quite comfortable. Study study study. The next time the Beast wanders in she'll ask him when he was planning to tell her.
"You're my friend," she offers after a moment. "You - you've been treated with appalling unfairness, and there's a sort of openness to you that I half-admire, and you have quite a smile. If unbeknownst to me that added up to love on my part I believe the curse would have noticed, though."
"Well, I am," says Belle. "I've - a handful of people have claimed to be in love with me before. But these were always people who'd barely spoken to me. Who thought I was pretty and knew nothing more about me than than that. If that was any kind of love I don't think it was a worthwhile sort. But if my merely looking as I do sufficed for you - for the curse - then I'd have seen it the first time I looked at the fondement, I think."
He trails off, thinks, then starts again.
"What's most beautiful about you is your nature - what you are, what you do. How you think, how you speak, what you say. Thunderstorms are beautiful for the same reasons—not the same things, not the same qualities, but the same... parts of them. Their essence and how they express it in the world."
"I'm pretty good at feeling how I want to feel, but I have to know what I'm doing," says softly. "I can decide to - to not be angry about something, if I want, because I know what it's like to not be angry. But I don't know what it's like to be in love. Even though I'd like to be."
...not very specifically.
Apparently the exact shades vary from person to person. There is an incomplete list of which emotions are usually associated to which hues; romantic love is indeed sometimes violet. And the exact shades are consistent between repeated viewings by the same enchanter, so an experienced enchanter can learn to distinguish emotions very well if they have the patience to study live examples.
