What does it mean to fight hard, but always make a joke?

In fact, my personal understanding of this sentence is this: the other party may want to say that it may be just a joke that you can't get rid of. In fact, both of them are possible, and both of them may be optional, rather than blindly unable to bind. Perhaps this sentence also reflects the other person's epiphany about love or other feelings. what do you think? The above is my answer, which may be inaccurate or incomplete, but I hope it can help you. Of course, if you feel good, you can also use it.
