The kind of action he said is actually that he is ill, you will buy him medicine, and you will take care of her for him before and after bed. I just care about him. There is also a birthday or any special day, you will buy her some small gifts and give her some surprises.
In fact, this kind of love action is very natural. For example, when you cross the street with her, you will hug her shoulder to keep her away from you and make him safer. Or when climbing a mountain, hold his hand and don't let him fall. This is an act of love, and you can't help it.
