You have a plum right there on your back!

But what I love just as much is how Tohru too is able to make Kyo slowly open up and trust her, to the point that he allows her to casually touch his beads, the symbol of his deepest vulnerability.

After Tohru's unwavering acceptance of Kyo’s True Form, the topic not only ceases to be a secret but also stops being a taboo. Kyo allows her to subtly refer to it without feeling bothered.

He goes from hiding, trying to run away and actively avoiding dealing with it...

to not being fazed by Tohru casually touching his beads and subtly referring to it

and eventually, he becomes comfortable enough to even talk about it.

The beads represent one of his darkest secrets, and it's beautiful to see how he learns to trust Tohru and to be comfortable talking about that subject with her.

But at the same time, it's also heartbreaking to know that the person he learns to trust the most is also the one he cannot share his actual darkest secret (his alleged responsibility in Kyoko's death) because he's terrified that Tohru will hate him for it.
