The "someday" written by 17-year-old Tongsheng beside Lu Jinhuai's name countless times came true 10 years later.
But in my memory, the two 17-year-olds were still back-to-back, and neither of them dared to turn around first.
It wasn't until the 27-year-old Hitomi revealed all the mysteries left in his diary from 10 years ago:
To Lu Jinhuai ten years from now: I really want to be the "someday" you wish for.
To the student from ten years ago: I hope you have me in every "one day".
