In the clear and shallow time, you around me shine with your own light, extremely bright.
Everyone has their own obsession
"Your letting go back then gave me a reason to never let go." Ye Sen's obsession was to fall in love with Qiao Chu, and from then on there was no one else in the world.
"I don't want to go back to the past, and I can't start a new life. I can't choose." Qiao Chu's obsession is that he thinks too much and has too many worries, so he can't choose.
"Chuchu, just be happy." Russell's obsession is because he loves one person but can't let go of another person.
"Why reject me? If you like it, I can become him and completely replace him. I am willing to become anyone you like." Qiu Jingnian's obsession is to simply love Qiao Chu, regardless of everything else.
