Regarding this, I think it depends on what kind of relationship you have. If you are really just good friends, then you can give him a life-size doll of a basketball or football. Boys generally like sports, so you can choose a sports style he likes and make a corresponding life-size doll. As for where to buy it, you can order it online, which is very convenient. Just send the photo to the online store, and it will be ready. It doesn't take a long time.
If you like him a little, why not take the opportunity to confess? Love always belongs to the brave. If you really like him, tell him. I suggest you choose DIY chocolate, engrave what you want to say to him in it, and then give it to him. You don't have to say anything to his face, a caring boy will definitely understand. In addition, chocolate is a symbol of sweet love and a good omen.
