This shows that male students confessed, but confession should not succeed. It shows that he is not discouraged and decided to continue to refuel, so he wrote this personalized signature.

He must have fallen in love with a girl recently, but he didn't find the right reason and opportunity to find someone else, so he changed his signature, but there must be signs. For example, this boy recently interacted with more girls in the circle of friends or got a little response from the other party before changing his signature, indicating that he had a good impression and was embarrassed to express it.

In short, this personalized signature is also very good.
