There also other moments like when Ame brought up the fact that she is the 2nd most subscribed vtuber and Gura sort of froze up awkwardly show that she is uncomfortable talking about her numbers.
Maybe 'ashamed' is not the right word but the fact that people here even have to question whether Gura will celebrate her 3 million or not shows that she rather uneasy with the whole thing.
