"I love you." What a vulgar three words.
I love you because I need you to love me. The simplest and most direct causal logic in the world, but there is a hint of conspiracy in it.
Love, in fact, has nothing to do with this, and has nothing to do with the established happiness in this world. It is only related to you, to me, and to the years.
Therefore, many people never mention it.
I love you, never say it;
I love you and I will wait for you in the depths of time.
