Create a lively and colorful illustration celebrating Valentine's Day with a vibrant gathering of anime waifus. Depict a group of diverse and stylish waifus in a beautifully decorated café, watching the viewer with love and offering thoughtful gifts. Surround them with festive decorations like heart- shaped balloons, streamers, and twinkling fairy lights. Include a table filled with an assortment of cute and delicious treats, and a backdrop of pastel- colored walls adorned with whimsical art. Add a banner with the words 'Happy Valentine's Day' in a playful, bubbly font, and ensure the overall atmosphere is warm, inviting, and full of friendship and joy
