It is adapted from the extremely tortuous teenage love story of real people.
The two fell in love in junior high school, then separated and reunited in high school, then missed each other in college but did not contact each other, and then...
"I can never love anyone else after leaving him. No matter how many decades have passed, how long his name has not been mentioned, how strange he is, I still love him."
Not for anything else, just for remembrance. Just to pay tribute to the purest teenage love. I only write for the purest, deepest and most unforgettable love.
It ferments quietly with time and settles quietly, just for the most ignorant and affectionate seemingly frivolous promise "I will not marry you unless I am in this life."
