If you like a girl but don't dare to express it loudly, you can express your feelings in a tactful way by giving her gifts during festivals, so that you won't be embarrassed even if she refuses. Here are some suggestions for you, and I wish you success!
1. You can customize a silver necklace for a girl, the kind in the shape of a heart, with her name or constellation in the middle. I believe she will understand your thoughts after receiving such a gift.
2. Buy a box of chocolates for the girl. This gift is very popular, but you can choose DIY customized chocolates and write some blessings on them.
Give the girl two movie tickets, choose the most popular blockbuster nowadays, if she says let's go to see it together, then she definitely accepts you!
