(Thank you @sleepywolfes for requesting this!!)

He's very intelligent and has a firm knowledge about health since he makes sure he is extremely healthy, he is a model after all and he cannot afford to throw that away due to getting an illness so he always made sure his health and looks were in tip-top shape alongside knowing signs of such illnesses.

So, he knows what Asthma is and when you told him you had it, he made sure you did things to prevent asthma attacks from happening with all the knowledge he had. And when i tell you he made you do the things strictly, i mean it.

He did see you as a friend so of course he would make sure you followed strict rules about what to do to prevent an attack from coming up out of nowhere or in any case.

You were well-known and well-respected for the work you've done for night raven college and sometimes, you were so occupied with many tasks that you usually ran around and did the tasks which, of course, led to a lot of asthma attacks.

In fact, Vil was the one always giving you inhalers that he advised you should always carry around.

And today was like every other day, you running around doing tasks for the other pomefiore students and many others. You obviously were beginning to have a asthma attack but you forced yourself through it and now, here you are.

You were in Vil's room as you took puffs of the inhaler as he spoke,

"Potato.. Have you learned your lesson after 11 times this has happened?" he said, he was obviously concerned and worried though, who wouldn't be? It made him a bit sad seeing you like this most of the times just because you overwork yourself and think you HAVE to do everything for everyone.
