Su Jin, a sophomore in high school, fell in love with the blue-toned deep sea and kept painting similar to it. She thought that there would be no one she could miss in her life. Until Jiang Lin, a later transfer student, met her for the first time in class, but the new transfer student looked at Su Jin on the rooftop. Jiang Lin looked at the painting and then at Su Jin, saying that your painting is very beautiful.
Later, they fell in love with each other and began what was called love in school.
The final ending is a girl standing on the beach, she said with a smile
"Su Jin... You liar... We agreed to go to a farther place to see the sea together... Why am I the only one left..."
.....
"I just want you to come back... Su Jin..."
In the days that followed, there was no more that girl on the beach.
