What does it mean for girls to send "Trojan horse" in short messages? What's the point? And often "hum", is there any special meaning? Please answer separately. Thank you.

Trojan horse, like everyone's conclusion, is an onomatopoeic word for kissing.

Generally speaking, it is more of a reward psychology, expressing joy and approval. This kind of reward psychology is that there is a princess complex in it, that is, if you do something that makes her happy, she will feel as happy as a spoiled princess and give you a kiss as a reward. I interpret it here as reward and encouragement.

Hum, of course, it is also an onomatopoeic word with no practical significance like everyone else.

Well, I don't agree with you, of course, but I'm not unhappy because of this disagreement, but happy. It means to be spoiled, that is, to pretend to be angry and make you coax. At the same time, hum is also a word that feels like a princess, indicating that she is disdainful of opinions and has the right, ability and initiative to disdain. In other words, she doesn't agree with you. As long as she doesn't agree with you, she has no choice but to coax her.

Whether it is reward, encouragement or coquetry, it is a feeling of a little princess. This kind of relationship mostly appears between a strange little girl and her little boyfriend, as well as between father, daughter, brother and sister and friends. In short, she regards you as a very close person, a lover with a high probability, but a brother with a high probability.
