Have you ever heard of such a kind of love in the world? We can only choose to hurt each other to remember each other. It's not that they don't love each other enough, they just can't love openly.

These have all become black feathers in the sky, accumulated on the bustling memories, and slowly will never see the light of day. Sometimes we don't love each other, it doesn't mean that the promise at that time is false. We sometimes?
