Why do girls scream uncontrollably when they see handsome male celebrity stars?

Cat Bro still can’t figure it out to this day—who can tell me what that feeling is like? 🤣
This video was taken by Cat Bro when he passed by the intersection at the time.
Back then, handsome Pita (พิธา ลิ้มเจริญรัตน์ Phitha Limcharoenrat), Thailand’s prime minister candidate, stood on the car and waved at everyone, and the girls’ screams in the crowd surged one wave after another.
(My ex-girlfriend was also his fan. I heard he was coming to Chiang Mai, so I was supposed to take her to the scene. I guess if she saw the person in real life, my ex-girlfriend would probably scream too, haha. In the end, the surrounding area was packed solid and traffic was completely blocked, so I could only drop her off nearby, and the rest of the way she had to walk over herself 😂)
