That's more than shy. It's people pleasing or even a part of mental disorders like ADHD haha11
Whenever am cornered with a topic or conversation that exactly isn't my cup of tea, i panic and say something agreeable to others but opposite to me i have a habit of saying that other party likes hearing so just i could get out or get them to leave me the heck alone
Cus thats actually how most of us shy person feels 24/7 I be overthinking every little things fr
