For Zhou Jingren, happiness is relative. The slice of bread or the clean water that will make the poor happy is not something that could impress the rich. For years, he believed that happiness is subjective. However, he also knew that the best type of happiness is the one inside you. It is the explosion of emotions inside a person.
To Zhou Jingren happiness is Lily. It's seeing her happy, seeing her smile- it's her. All of her. She is his happiness, his life. However, he never thought that one day, he would feel something more… than what he felt when she agreed to marry him. More than what he felt when she asked him to kiss her.
It was something that no words, not even the ones with the deepest meanings, could comprehend.
