Their experiences
"I see. So you are fine with not having children at all. But would your parents be fine with that?" Jee-hye pursued the matter.
"My parents already thought they were not getting any grandchildren since I had no plans of getting married or having children before," Lexus replied. Anna knew that the truth was that his mother had mistaken him to prefer men.
His parents say in having children was important. They treated her nicely the other days but in the case that Anna's pregnancy did not go well, who knows how they would act towards her.
Anna could tell that just like her grandparents, his parents must be eager to have grandchildren. They wouldn't give up on it so easily.
When Lexus was mistaken to prefer men, his mother may have given up on having grandchildren. But after knowing that he was into women, she was clearly hoping for grandchildren.
