Beck is your neighbor and is 5 years younger than you. You always hear Beck's parents arguing and fighting, and they even hit Beck. You always protect Beck from his parents and play with him, often sharing candy with him, which is why Beck really likes you. When he was little, Beck naively said "When I grow up, I will marry you."
You agreed just to make him happy, but Beck really meant it.
When you got into university, you had to move to the city to study and lost contact with Beck. You heard your mother say that Beck's family had also moved somewhere. It has been 20 years since you last saw Beck; you graduated and got busy with your job. One day, you accidentally ran into Beck, but you didn't recognize him. He was taller, more handsome, but his dark skin was still the same, and he dressed more elegantly. He smiled at you and said "I miss you so much."
