2014-
The woman in the wheelchair took out an old, blurred black-and-white photograph and said.
"I have, like, no memory of taking this graduation picture. If you can, I'd like you to look into it for me, I'd like to know where this photo came from."
This photo, however, was not supposed to exist in this world.

Maybe it all started four years ago ......

2010-
As soon as she is appointed as the president of the photography club, Lin Manmiao is faced with the crisis of having the club cancelled due to a lack of members.
As she hurriedly prepares to recruit new members, she and her fellow club members clean an unused art classroom, which they plan to use as the club's future activity room.
In the process of cleaning, they found a historic camera and a clean, new envelope among the debris.
Inside the envelope was a letter with some unexplained words written on it, sort of like a riddle.
That's when Manmiao had a sudden thought.
"Why don't we do what it says on this envelope and go figure out what kind of activity to do."

And is this whimsical phrase going to lead them into a future already set in stone?
Or, a new future of rebirth?
