Do u think she put the 🏳️‍🌈 in her Instagram bio page for someone or no?

The other day at work I saw this guy who went to my old high school & he’s friends with this girl I used to like back in school. But he doesn’t know me I think. So then later when I went to my old high school crush instagram page I saw that she put a 🏳️‍🌈 in her Instagram bio.
