When we are young, we have nothing but courage.
If it were possible, on a certain day of that month, in a certain period of the past, or at a certain moment in the future, when the familiar prelude sounds again, would you still be willing to hold someone's hand and carry your love to the end?
In everyone's life, there are always people appearing and people leaving. After experiencing it, we understand that love needs to go through a chemical reaction and be sublimated into love before it can flow smoothly.
