Sun Yuan never believed in the saying that love is like a moth flying to a flame. She is not greedy, and since she was a child, she will not feel comfortable possessing anything that she has obtained effortlessly, even if it is love. Maybe she was moved and felt sorry for that person, but before sinking deeper, she would be willing to stop and just have a taste.
But Bai Qiucheng was just the opposite. He would not let go even to the end of the world. He is such a person, if you are willing to give him your hand, then he will tell you: I will take you anywhere.
So when Sun Yuan met Bai Qiucheng, she couldn't escape or forget, she could only be intoxicated, like a moth to a flame.
