This girl is suddenly asking me to meet in a mall this Saturday. Should I be cautious about it?

There is this girl whom I met on Okcupid dating app on December 2022 when she was 18 about to be 19 soon and I was 21 turning 22 very soon. Now i am 22 and she is 19 and we started following each other on Instagram. She just entered 2nd year of college and I just graduated college 2 weeks ago and about to study MBA next. Idk she was kinda ghosting me but suddenly chatting in between occasionally. But we again had been chatting on Instagram for the past 2 days and today suddenly she told lets meet on Saturday in a mall. I might be having classes on Saturday as I started going for an institute to prepare for exams to get into an MBA B School. Should I really be cautious as she was ghosting me most of the time and suddenly asking me out like that? Plus I have a massive crush on this girl Anshika in our class who is also 22 and 3 days ago I came to know she finds me cute too. So should I avoid meeting her and focus on Anshika now?
