When the boy was 18 years old, he met a 16-year-old girl. The boy fell in love with the girl when they first met, but the girl didn't know it until the boy passed away due to an illness. His friend told the girl about the boy's feelings. The girl felt stupid when she thought about what the boy said and did to her before. She couldn't help but think that if she went back to the past, she would never let the boy bury his love in her heart.
Intention: The lost person will never come back, and the belated love is gone with the wind.
