1. Start by getting to know him better. Try talking to him in class, at lunch, or after school. Find out what he likes and dislikes. This will help you build a connection and make it easier to ask him to the dance.
2. Once you feel comfortable talking to him, try dropping some hints that you're interested in him. You can do this by flirting with him, making eye contact, and smiling at him.
3. As the dance gets closer, start asking him about it. You can casually ask him if he's going and who he's planning to go with.
4. When you're ready, just ask him to the dance. You can do this in person, over the phone, or through text. Be confident and straightforward. Let him know that you would love to go to the dance with him.
5. If he says yes, great! You can start planning your outfits and transportation together.
6. If he says no, don't be discouraged. There are plenty of other guys who would love to go to the dance with you. Just keep trying until you find someone who says yes.
