At the beginning of the story, you asked: "What do you think is needed to start a formal relationship?"
I say: A formal confession to sign a mutually agreed upon contract.
At the end of the story, you say, "I'm really sorry, you deserve someone better."
How did it come to this end? There was an encounter, and we didn't reach the ending we expected. I really don't understand, but my pride tells me to stop here and wish you meet a better person.
Purpose: Study hard, improve yourself, earn a doctorate along the way, and build a beautiful China.
