It must be said that as long as it is a gift, anyone will be very happy to receive it, not to mention that it is a gift from your boyfriend. It is normal to be busy at work. I think she will understand your work very well, so she will not care about these things with you. But when there is a suitable opportunity, you should still show yourself well. After all, you are a couple. You should give her such a warm feeling. Giving gifts on New Year's Day is also a kind of New Year's new atmosphere. I think you can give her gifts from the following aspects.
1. Expensive gifts such as jewelry or watches are the most attractive gifts for girls.
2. Creative gifts, simple and creative gifts such as DIY chocolate, couple cups or couple rings.
3. Create some romantic feelings, give her a bouquet of roses in a western restaurant, let her have the initial enthusiasm. Or repeat the scene when you first met, she must be very moved.
These are my suggestions, I hope it helps you.
