Was she offended in any case because I offered her a can of coca cola which i already drank half or am I overthinking?

Today i again met my crush Akankshya in the classes where i go. I have shared before that she is very pretty almost model like and is in the 21-23 age range and I am 23. We had been having brief conversations these days and today again we met. I was drinking a can of coca cola that time so I offered her whether she want to drink some too even though i already drank half a can already. But she said no thanks. She smiled and said it but i am worried whether she got offended because i already drank that can half and still offered her. She was also with her female friend so the conversation was brief and she said she had to go practice for the upcoming Fashion competition where she is participating. So we showed each other this 🤟 hand gesture while saying bye to each other. One of the guy from our class said me that I should have bought her another can of coca cola instead. Do you feel it was kinda bad of me to offer her like that?
