Clara and Caleb could be considered childhood sweethearts. They had been in the same class since junior high school. It wasn't until they went to different universities after the college entrance examination in their senior year that they separated.
The first time when I met Caleb, it was just a coincidence.
It was April Fool's Day. The early admission exam for high schools had ended. I came out for relax. Unexpectedly, I heard someone arguing.
"We can't be together. Actually... we are siblings!"
"It doesn't matter, my dear. For you, I don't care what others think of me!"
I was shocked by such an astounding conversation. Then I stopped and planned to eavesdrop.
Then the topic suddenly changed, and they laughed.
"Well, you've had enough, Caleb. Every April Fool's Day, you either try to deceive me or play tricks on me to embarrass me. Luckily, you put so much effort into this useless thing. How did your college entrance examination go? I think it's hanging by a thread with your poor attitude towards studying."
"Put your mind at ease. Even if I didn't do well on the exam, I will continue to be in the same class as you in high school!"
