An older girl flirted with me in the park.

So, I (18M) was sitting in the park at around 8.45 just watching anime on my when suddenly a girl says excuse me and I look up and she says "Sorry I mistook you for someone else" I was like alright no problem.

She goes away and after a few seconds she comes back and says "Hello, Btw you're really cute" I was flabbergasted and I said Thank You very much, She proceeds to say your glasses suit you really well and your jaw and lips also look this influencer I know and your curly hair make you look cute. I was blushing and smiling like wtf this is the first time this has happened to me, she says my physique is also good (I was wearing a muscle fit button up shirt), I said you're also really cute (She was), then she asked me for my age and I said 18 she was shocked and said "YOU"RE 18!?" I said, Yeah? She said I thought you were older around 20-22, then I asked her for her age and she said 22, I was shocked cuz she had a baby face, she looked 17-18 but whatever, She sat down next to me and started talking about all sorts of stuff, She asked me for my cast(ik weird) I said I'm muslim, She said she'd have definitely pursued me if I was a little older and not a muslim, me being an introvert just listened to her and replied, we talked for around 20 minutes She told me atleast 5-6 times that I'm cute, I was hella flustered ,then walked together as our home were in same direction, I got her IG. But holy shit that was a weird experience.
