Help me pls

Hey guys!! Hope you’re all having an awesome day!! 🥰

So I’m in high school 3rd year and I like this guy and I feel like he’s been flirting w me(cuz he’s being super annoying and always kicks me under our desks and stuff). I want to get closer to him but I literally have no idea how to initiate a conversation. 🥺Please please give me some advice! Literally any suggestions would help!

Thank luvs💕
