Viktor has three paintings commissioned the very first time: one of him, Yuuri, and Yura, another featuring just him and Yuuri, and finally, a third one of Yuuri that only three people in the world will ever have the privilege of seeing because Viktor might just commit the most gruesome of murders should anyone else other than him, Yuuri, or the artist, sees it.
It, being a painting of Yuuri in complete dishabille, modesty preserved only by artfully placed swathes of silk and jewelry.
