Dude, it's been 10 years.... she's definitely interested. Probably.
Make up some bogus tiktok challenge with a list of questions she has to answer. Slip: "Do you like me?" In the middle of the list.
Make sure to video it with your phone so it looks legit for tiktok..... but really, you can study her response to dylm? over and over for years to come looking for clues to if she really does like you.
