I can't wait for the Big Talk, especially because of this chapter. Yuuri being absolutely appalled at Viktor's perspective of that night. Obviously, he already knew it was a mistake, he hurried away ashamed of himself, but he didn't have a full picture of just how hurtful he had been. At the same time, I want Viktor to know that as fucked up and inexcusable it was, he was never "just a random body to use". Ir could never be anyone but him to Yuuri.
Yuuri is shocked and horrified that he hurt Viktor so badly and that his actions came across so awfully and Viktor would be ecstatic that, bad as it was, Yuuri was only ever thinking about him the whole time
