Reminds me of that other "married in an MMO" series where MC confesses, gets rejected and when they ask the girl why, she says it's because "girlfriend" is a downgrade from "wife".
Dumbass is trying to confess to a girl who already thinks of herself as his wife. Who, just a few moments prior, made him change calling her his online friend to calling her his wife. He's one dense motherfucker.
