What would your reaction be if you ever met your favorite celebrity or idol in person?

I always imagined I'd be incredibly composed, perhaps offering a simple 'Hi, how are you? Be happy!' But now, I'm not so confident. Just recently, while watching the K-drama Resident Playbook, Yeonjun and Soobin from TXT unexpectedly made a cameo appearance at the very end! I was ecstatic – practically jumping and screaming with joy. I completely lost it! I truly hope I wouldn't have such an over-the-top reaction in real life; that would be incredibly embarrassing . Of course, the chances of me actually meeting them are practically zero, a mere one percent, or perhaps a true miracle.
