When they were born, they were on the left and right of the crib.
When they met again at the age of three, their houses were on the left and right of each other.
When they go to school, they sit on one side and one on the left.
For so many years, one of them has been on the left and the other on the right. It is fate, but they have always been in parallel with each other tacitly.
This is a story about a pair of childhood sweethearts who fell in love and killed each other. It is neither cliché nor cliché.
