If you were me, what gift would you give him?

Make yourself a present. I can see that you should be a girl, so this gift should not be too thoughtful, because you are good friends. I think it's good to make an album by myself. Write a few words on it with a highlighter, or write some English, or draw some pictures. If there is a picture of him, you can post it. If not, it doesn't matter.

Or you can make your own desk calendar, and the artistic font looks better (that boy should belong to the cold type, so don't spend too much, just use black and gray as the main tone)

Then if you don't like the first two, I think you can fold paper cranes, stars and hearts. Paper cranes can be made into wind chimes. That boy will naturally think of you when he sees the paper crane hanging by the window. The same is true for folded stars, which can also be put in glass bottles.

If you don't want to do it yourself, it doesn't matter. Buy a constellation cup with his constellation on it. He will think you are considerate and know his horoscope.

Or buy a bracelet or necklace with his initials (if not, you can buy a mysterious necklace, hehe)

Or, if you go to gift shops like Xiaoqi and Dejili, there will be something you like.
