@Avgvstvs It looks like the new version is a higher-quality raw and has better redrawing/typesetting (actually cleaning up the speech bubbles instead of layering English over the Japanese), but it's using the same translation from the original.
@Vinji you didn't miss anything, in the LN they decide to call themselves Shin's fiancees so they won't be bothered at the party. Manga adaptation decided to skip that, oddly enough.
@mongol13 it’s to hide Schnee’s identity so she doesnt get swarmed. She mentioned earlier that she used a spell to conceal her identity, thus making up the name Yuki.
