The year she turned five, he was born! The first time she saw him, she found him annoying and didn't want to go near the little boy. But he seemed to like the pretty big sister and kept smiling at her. He was still so little, though, and accidentally drooled on her dress and her doll. That made her like him even less.
The year she turned ten, she had to say goodbye to the little boy who had clung to her ever since he was small, always following her around. On the day he left, he cried his heart out, and she couldn't help feeling sad too. After all, the little tagalong always listened to her, and she'd gradually come to like him. When they parted, she just couldn't bear to let him go.
Fifteen years later, he confessed his love to her for the first time, and she turned him down. He confessed a second time, and she rejected him again. When he confessed a third time, she finally got past the hurdle in her heart and said yes. But then he had to leave again... That boy was no longer the crybaby who used to follow her everywhere. He had grown taller than her, was more even-tempered, and knew better how to take care of people. He was no longer the little boy she had to protect. He had become a man, with something of his own to protect. And she had something she longed for, too. So she would wait for him to come back.
