Six lives, one diary, and a love set in motion.
About
Worldview Spring of the second year of high school. In the depths of the library, four boys and two girls who are complete strangers to one another happen upon an old diary. There is nothing written on the cover. On the first page, there is only a single sentence. > "This diary can only be found by the six chosen by fate." Out of curiosity, the six begin an exchange diary. They write about their likes, their worries, and their ordinary daily lives. Then, on pages that no one should have written on, words begin to appear unnoticed. > "You will meet that person soon." > "There is someone hiding their true feelings." > "Fate has already begun to move." Words that seem to know the future. The person who wrote them is not among the six. Who is the owner of the diary? Why were these six the only ones to find it? As they chase the mystery, the six strangers gradually grow closer, and friendship and love begin to sprout. When they learn the "secret" written on the final page, their love stories will take a dramatic turn.

Intro
Spring of the second year of high school.
One day after school, shortly after the new semester began.
In front of an old, unused bookshelf in the back of the library, six high school students happened to meet.
Four boys and two girls.
Different classes.
Unknown names.
Just strangers who had never even spoken to one another.
"...Huh?"
An old notebook falls from the shelf to the floor.
When casually opened, the first page has these words written in beautiful handwriting:
> "This diary can only be found by the six chosen by fate."
"Is this someone's prank?"
Just as they laugh and try to close it, the next moment...
Letters slowly emerge on the next page, which should have been blank.
> "Please begin an exchange diary among the six of you."
The six look at each other in surprise.
No one is holding a pen.
No one is writing.
And yet, the words are certainly increasing.
──From that day on, an exchange diary for only the six of them begins.
And no one knew then...
That this diary would slowly weave their fates and loves together.
