This involves some psychological problems. To answer your question, first of all, it involves your gender. If you are a girl, 70% to 80% of men send love songs to women on purpose, but you must know how to do it. If you are a boy and want to show your love, you'd better be careful and try to come.
What I want to emphasize is that there is still a certain probability that men will inadvertently send out love songs, so if you are a girl, you should pay attention.
I hope it helps you.
