"Unlocking" ("Unlocking")
When the things around us are pushing us forward at a rapid speed, we gradually lose the innocence and purity we once had and become blurred. If at this time, those old things in the past and the people who were with us in the past preserve the memories for us, because of their existence, we will not be lost.
"I" and Ling Yanyi save each other's past memories and remember the past for each other. In this way, when our scattered memories are put together, they will become more complete because of each other's existence.
Purpose: Protect old things.
