The founders might be quite surprised by the Golden Trio. They could be impressed with their skills and knowledge. For instance, Hermione's vast magical knowledge would surely catch their attention.
If it was a harmless touch, you can just smile and let it pass while gently teaching the child about personal space. For example, you can say 'We should ask before we touch someone.' But if it was inappropriate, firmly say 'No' and remove yourself from the situation. Then, tell a trusted adult like a parent or a teacher.
Given that K - pop idols often have a positive image to maintain, they would react in a very positive and family - friendly way. They could share some interesting stories about their journey in the K - pop industry with the 13 - year - old, and maybe even offer her some words of encouragement for her own life, like to study hard and follow her dreams. This would not only make the meeting pleasant but also inspire the young fan.
She would probably be super excited. She might start screaming or crying out of joy. After all, meeting her favorite group is a big deal for a 13 - year - old fan.
He might be extremely embarrassed. A 10 - year - old is usually at an age where they are starting to be more independent and self - conscious, so dressing as a baby would go against that. He could also be angry at the person who made him do it.

The Golden Trio's reactions would be diverse. Hermione would immediately start making mental notes about the new magic education system. She would be interested in how they teach Charms, Potions, and Transfiguration in the future. She might even try to get involved in some of the classes as an observer. Harry would be looking for the sense of community and camaraderie that he had at Hogwarts. If he doesn't find it in the future's system, he would be disappointed. Ron would be a bit overwhelmed by all the new gadgets and advanced magic used in the teaching process. He might long for the simpler days at Hogwarts, but at the same time, he would be curious about the new things he sees.
There's a fanfiction called 'First Year Redo'. In this story, the Golden Trio goes back to their first year and decides to focus on befriending some characters they didn't get to know well before. They also use their knowledge to prevent some small, but annoying things that happened in their first year from occurring again. It's a heartwarming story that shows how much they've grown since their first year at Hogwarts.
