There was little chance of desire fading. Even if on the off chance in this or the next life or the next (it needed to stop, he needed to stay) they hit a barrier of sorts, the underlying desire to stay by the heretic's side would remain. Ty, for all he objected and all the noise he made, knew that feeling and it caused much of the confusion. He was stubborn, as he would ever be, and not everything had settled yet. It would, in time, and he would know and the bubbling memories and compulsions would finally ease into sense.
If he had to live a life as a bug, though, he'd probably end up incredibly unhappy. Bugs were not okay. Annoying, invasive, and just generally not pleasant. But as a cicada, he could do all the shouting he wanted, at least. Not that he hadn't shouted plenty in each life so far.
In a way, Ty was positive everything about them took the relevant parts of Buddhism and turned them on their heads. Everything in his life had dragged him back to Goku, more or less, so it was tough shit for the way of the universe.
He'd never openly compare it to feeling "right", but between the kiss and and the familiarity and the desire for it, that was as close to a good name for the feeling as he was likely to ever get. Because it was. Constantly finding something he'd never noticed he'd been missing.
That gentle touch sent a faint shock down the back of his neck, radiating outward and ultimately disappearing between his shoulders. Normally, Tài Yáng was stingy with kisses, keeping them brief, denying the languid affection he was almost compelled to grant (it was overwhelming to feel so strongly when you didn't understand it entirely, and so he balked). But at the moment, he wasn't really all that inclined to follow that habit. Even less so when the kiss began again. He did the opposite, encouraging rather than breaking away, moving his free hand to Goku's shoulder for lack of any idea where to put it just yet.
