Boys and girls seem to have no resistance to these things, hehe.
You can always take him with you. Crystal also represents love.
I bought a crystal bracelet for my boyfriend at Jiuxiu some time ago. I like it!
You can go up and have a look.
I want to give him a special surprise at the hour. They have a gift delivery service at the Nine Show. You can ask the seller to put a card in it and write what you want to say to him. It's up to you.
This will allow him to receive your gift to him without knowing it in advance.
The effect must be good! I hope I can help you ~ hehe ...
