It seems that he seems to care about you. Give him a customized gift, such as a customized men's agate bracelet. It is not only face-saving, but also he will like it. The agate can be engraved for free. You can engrave the other person's name or surname. Such a special gift just represents your heart. There is also a magnetic pure titanium steel anti-fatigue bracelet. Men's pressure is several times that of women. They are more prone to fatigue. Give him this gift to let him know that you are willing to solve his fatigue. If he is careful, he will understand your intention.
If he is still like a big boy, he must like strange things. It is better to give him a puzzle puzzle, or nine-linked rings, magic, Rubik's cube and other gifts, which should be a little special. You can also customize a special birthday cake on his birthday. It would be better if you can make it yourself. Watches, briefcases, men's perfumes, these gifts can also be given. The packaging should be as delicate as possible. It would be more perfect if you can attach a small card designed by yourself.
No matter what gift you give, you must put your heart into it. Only when you put your heart into it, the other person will see your intentions. So if you want to continue to develop the relationship, you still have to spend more time thinking about it.
