When Su Jin'an was ten, she met an older boy who would dazzle her throughout her youth: Jiang Qi, her stepfather's son.
At some point, Su Jin'an realized that she had fallen for her stepbrother without even noticing. At her best friend's urging, she began finding all sorts of excuses to show up in front of him. Jiang Qi thought she was just a little kid who liked to fool around, until one time, when Su Jin'an was running a high fever, he heard her mumble in her sleep and realized things were getting out of control. Gradually, he began to take her seriously, even making a promise that he himself thought was ridiculous.
"Big brother, I really like you. Will you marry me when I grow up?"
"All right. I'll wait for you to grow up."
The promise they made as children endured years of hardship. Time proved their love.
Many years later, one day...
"Big brother, I've grown up. Do you remember what you promised me?"
"I remember. I've come to marry you."
