Wanderer had grown accustomed to seeing the cracks on his skin. In a twisted sense, he was rather fortunate. If he was human, the damage would've killed him or worse. One good thing about being a porcelain puppet is being able to put yourself back together no matter how many times you break. Still, the cracks never went away. His scars won't fade.

That wouldn't be an issue if he didn't have to explain to people why his skin was breaking like glass. So concealing it with various cosmetics became routine. But even that couldn't hide it forever, if the weather soured or a fight got too violent it would end up washing off.

That's how he found himself sitting still, albeit by force, while you applied lacquer over his old injuries with a brush and dusted it off with gold powder.

"Don't you have better things to do?" He understood the concept behind Kintsugi, he wasn't dumb. What he didn't get was why you'd waste your time and resources on this.
