How do you say the opening words of the first text message to a female classmate?

Send it like this: Hehe, hello, this is the opening remarks. In fact, don't be too restrained, and don't rush to the subject as soon as you come up. Let's start with a simple prologue. Although the opening of "Hehe, Hello" is idiotic, what matters is this idiotic feeling. I remember little girls like some lovely ones. Just pretend to be cute, and then ask common topics, such as: What are you doing? Or have any hobbies or something. Anyway, the first few chats should be normal, not too direct, so that the other party feels that they have no sexual desire. When they get used to chatting, they can gradually deepen the topic, deepen and deepen, and finally it's up to you.
