The protagonist of this novel is a poor boy with a miserable life experience, indifferent heart, and even some lack of ambition. The special growth environment made him exposed to the warmth and coldness of people's hearts earlier. He can easily understand people's hearts and hates the hypocrisy and duplicity of this society. When he had no illusions about the world, he met her - the girl who was worthy of him changing himself and spending his whole life to protect her.
Sometimes, it's not that you're too lazy to work hard, but that you haven't met anyone worth fighting for.
Meeting each other in a vast sea of people is a blessing in itself. And some people, once you meet them, you know they will last a lifetime.
