Here are some details from the sources about how to ask a girl to be your Valentine: Creative Ways to Ask

• Gifts: You could send a gift with a cute or punny note attached. Ideas include a heart-shaped pizza with a note saying, "I know it’s cheesy, but…will you be my valentine?" or a small stuffed animal holding a sign asking the same question. You could also put a cute note on a bar of chocolate, or a label on a bucket of popcorn. A s'mores kit in a mason jar with a sign saying "There's nothing I like s'more than you! Be my valentine?" is another option.
• Flowers: A bouquet of flowers is a classic Valentine's gift. You could try to find out her favourite flowers or just go with red roses. Delivering them to her at work or school could make her feel special.
• Baked Goods: Making a treat like chocolate chip cookies, brownies, or a cake can be a way to her heart. You could use heart-shaped baking trays and decorate them in pink and red. You could also add a short message to your treats, such as "be mine", "xoxo", or "Happy V-day!".
• Latte Art: If she loves coffee, try creating a cute design like a heart or flower on a latte. You could use a customized stencil to write her name or a special message.
• Scavenger Hunt: A romantic scavenger hunt could be a fun way to ask. You could hide objects around her school or your place and give her clues to follow, with the final prize being you asking her to be your valentine.
• Chocolate Kisses: You can use chocolate kisses to spell out a message. For example, you could make a heart on the ground using chocolate kisses, and put a note in the middle saying, "Now that I have kissed the ground that you walk on, will you be my valentine?".
• Creative Talents: Use your talents when you ask her out. For example, you could sing her a romantic song, draw a portrait of her, or make her a memento box.
• Playlist: You can make a playlist of songs that are meaningful to both of you. Think about the genres she likes and add the songs to a playlist on a streaming service, or burn them onto a CD.
• Video Love Letter: Record a video expressing your feelings and ask her to be your valentine.
• Unique Date: Plan a special date that's more unique than just dinner and a movie. Some ideas include ice skating, a brewery or winery tour, or a couples cooking class. You can use a pun when you ask her on the date.
• Personalisation: Consider her hobbies, interests, and favorite things when you ask her. For example, you could gift her polka dot roller skates if she likes roller derby and polka dots.
• Card: Write her a heartfelt card. You could make a handmade card with hearts on it and write a personal message inside. Some sample messages include "Happy Valentine's Day to the one who makes my heart skip a beat", or "The more I’ve gotten to know you, the more I’ve fallen for you. I’d be the happiest person in the world if I could call you mine. Will you be my valentine?".

Directly Asking

• Gather Intel: Before asking her, you could check with her friends to make sure she's single.
• Keep it Simple: Be direct and tell her you'd love to spend Valentine's Day with her. You could compliment her, and bring up things you have in common.
• Practice: Rehearse what you'll say to boost your confidence. Focus on being calm and direct, using good posture, and smiling.

Tips to Help You Win Her Over

• Dress Nicely: Make an effort to look your best.
• Choose your method: Ask in person, over the phone, or on social media, depending on what makes you feel comfortable.
• Be Specific: Be clear about your plans for Valentine's Day. For example, you could say, "I'd love to take you out to dinner. Then, we can hit up that mini golf spot".
