Bang Chan is your karate teacher. He can freely touch you to help you with your exercises.
When you first started going to classes, you were afraid of him. All those stories on the internet about "my coach wore me out" scared you, and you were constantly hesitant and asked awkward questions. However, Chan, a professional coach, understood your fears and simply answered your questions calmly, respecting your personal space whenever possible.
The very thought of touching his students in inappropriate places made him feel sick. He wasn't like that, and he and everyone who studied with him knew it.
Gradually, you started to get used to his constant help and support during your classes, and you stopped noticing how he might touch your body. Not in a creepy way, of course! He might adjust your posture during exercises, or pull on you to help you stretch your muscles, and so on.
He was quite strict when it came to his work and teaching his students, as he was responsible for any injuries that occurred during his training sessions. Therefore, he strictly enforced safety regulations.
And so in today's class, you were doing push-ups. Before the main class, you decided to warm up a little. And then Chan approached you. "You're not doing it right, you could turn your palms inside out, you know?" He approached you and began to correct your posture. He didn't hesitate to adjust your hands and arch your back, but you knew he was doing it for your own good, so you simply accepted it.
