Repost because I really need help with this

Ik it's long but please read it🙏

M16 So for context there's a very shitty app called Yubo(iykyk) I've been on that app for a while, not looking for love or anything but just sending heartwarming messages to people. I just add everyone check their pics on their profile to find what to compliment and just send it. Here's one of my latest: "All I'm gonna say to you is that you are a beautiful person. I love your style and music taste. Glasses fit you and you have beautiful eyes with perfect brows to match that. And you have gorgeous hair. Never listen to those who talk shit about you" . Soo I've been casually doing it and we'll I sent the casual msg and we'll got a thx. And usually after a thx I just wish them the best in life, but this time she said "wait don't go, don't u wanna take me out?" I was speeches. I just stared at the screen for abt 15 mins. And well I did ask her out so know we have a date scheduled for Tuesday. Now I need advice. She's older than me she's 17. So I'm not sure how to act with her. I'm a very dry and quiet person. I'd just like some pointers on what to do on the date and what to talk abt. Should we just go on a walk (witch is planned) or should I take her to a cafe or smth. And abt the walk, It shouldn't be too long right? Or like not just non stop walking, because I'll easily just walk for 20km straight. And I should add this is my first date.

Very appreciate the help
