Giving a small gift to a couple can deepen their feelings for each other. It is a small spice of life together, which can make each other always have surprises and uncertainty.
Of course, newly-started couples will give gifts a little more frequently, but this is indeed a way to increase feelings. Since he gave you a gift, you can't take it for granted. It's right to give him a small gift in return.
I recommend a color-changing water cup. When you pour hot water, it will change into a creative cup with photos. You can sit on it for your group photo.
Couple rings are a very suitable gift for couples who have just started, symbolizing vows. There are many other small gifts. You can carefully choose the one you like and give it to him. I hope it can help you.
