What happens when a boyfriend buys fake shoes for his girlfriend?

My boyfriend buys fake shoes for his girlfriend, and I think the consequences are still serious, because I think it is normal for boys to give girls gifts and things in the process of boyfriend-girlfriend interaction. In this case, although the gift is not particularly expensive and the price is average, you should at least be honest and not use those fake things to prevaricate and deceive each other. I think this is a person's moral problem. Let's talk about serious moral problems first. In this case, after the boyfriend buys fake shoes for his girlfriend, the consequences will be very serious, which is likely to lead to breakup and emotional breakdown.
