I sent a short message to my supervisor, asking him to remind me more at work. What will he think of me when he sees it?

Now your supervisor has replied, proving that there is no problem. Instead of paying attention to you, I can only say that only when you make achievements will others pay attention to you and your words have weight. Even if you are wrong, others will not have any conflict with you. To put it bluntly, it is your ability, your achievements and your strength.
