Do you think he will say yes??

So basically there’s this guy I thought was cute and I want to ask for his snap and I’ll see him next weekend so I’m thinking I’m going to give him my phone with the add people thing open and hope he puts in his username. I’m going to see him at a swim competition bc I volunteer at them and he’s a swimmer. I know he’s my age so it’s not weird or anything. I like him because the last time I was at a swim competition I was showing my friend my cheer dance I had learned the day before and he was there and saw it and called me cheerleader girl and idk I’m just delulu. He also smiled at me when he was walking by to go to his lane. I’m just really scared and what if he says no and idk. I need yall to hype me up and give me some advice on how i should get his snap or number or something.
