When I bought my boyfriend a couple phone case, he didn't want to use it for various reasons. I am disappointed to ask for one.

You can draft a statement like this. You can say that the couple's mobile phone case is carefully selected and I want to give it to my boyfriend. I hope he can understand my good intentions and is willing to use this mobile phone case for me. How can he accept it? Waiting online is quite urgent. If you think so, your friends will also comment on this matter and give you advice. In fact, you may or may not need an idea. This is a trick for everyone to carefully prepare the couple's mobile phone case, and it is also a disguised show of love. And your boyfriend can see that under pressure or when he sees that you really pay attention to it, he will change his mind to use this phone case. Or he will tell your boyfriend quietly that you want to use it after watching it with your friend. Your girlfriend said that, so you should use it. If your boyfriend is smart, he will definitely use it. I hope my answer is helpful to you.
