Really need advice.

So my boyfriend went to Cochella this year. He came back and told me he met this girl from Florida while he was there. I didn't think anything of it cause at Cochella you met people and have a good time. A few months later was his birthday and he received a gift card of $100 to gamestop. I asked him who it was from thinking it was this parents or brother. It was from that girl he met at Cochella. Should I be concerned that she is sending him gifts like this? I mean they met at Cochella and that was it. Please if I'm overreacting tell me. I'm just a little worried.
