Criminal Mind

One day, when Lin Chen was reading, Xing Conglian asked him: You are a psychologist, so can you help me figure out what kind of person I am suitable to marry? Lin Chen remembered that she told him at that time that love is the most immeasurable thing in the world. Even psychologists cannot predict it because the process of falling in love between people is full of countless variables. Xing Conglian asked again, what is a variable? Lin Chen thought at that time, the variable is, I thought you were just an ordinary policeman who likes to open a bottle of beer and eat crayfish at the food stall, but I didn't know that you turned out to be...; or, in other words, the variable is, I don't know that I will fall in love with you, and I don't know when you will fall in love with me.
