I just had this thought of how would the Twst boys react to a Yuu that makes self-deprecating comments, mostly when they make mistakes
*loses a game that they knew how to win but wasn't skilled enough* "I'm the worst*
*stood quietly during a conversation* "I was thinking... Wow, me? Thinking? That's new!"
*when someone acts surprised they said something really stupid* "I'm dumb, move on"
*when someone asks them for help with something they don't have experience with* "I'm so useless"
And some of them, like Kalim, Silver and others, react like "oh don't say that" and Yuu is like "don't say what?" bc they don't really realize they made comments like that and have already forgotten they did. But they eventually realize it's making others uncomfortable so they try to not say stuff like that, but in a "oh suddenly this isn't a safe place anymore" kinda way lol
I'm not sure how the others would react though...
