钥匙走了，锁在等待；许久，钥匙回来了，却发现，打不开锁了；因为锁芯生锈

The key was gone, and the lock was waiting; after a long time, the key came back, but found that the lock could not be opened; because the lock cylinder was rusted. The heart is like a lock. Once the heart is chilled, no matter how close you are, if you want to open the door of your heart, you will not be able to return to the past; cherish the person who is good to you, and if you lose it, you can't find it.
