What do you mean, I only sell Twilight on Earth to collect tenderness on earth?

It means that I am a person who can make the stationary earth turn. I improve my tenderness by restoring the earth's rotation in exchange for a large number of enzymes or neural structures involved in neural activities, all in order to make something with a "tenderness detector" appear or see some kind of illusion.

From the perspective of sentence structure: I only sell a to receive b and see C.

The premise of the "goodbye" action is to collect enough B's, which are both "gentle". The way to receive B is by selling A, which is "dusk". (It looks a bit like Zelda's task chain)

So the meaning of this sentence is probably like this: "You" is something that can only be seen through "picking tender", and the means I choose for "picking tender" is "selling dusk", and the place where I sell dusk is "people".

In other words, there are three strange premises: dusk can be sold, the equivalent used to buy dusk is gentle, and it is possible to sell dusk outside the world.

The truth of this sentence

Love is never a person's business. It is mutual understanding, mutual concern and mutual tolerance.

Long-distance love is the most admirable. They let love have no space and distance. Although thousands of miles apart, the hearts are together. Love makes each other care and have sustenance. In different cities, they work hard and pay too much just to live inseparable lives. They betrayed each other at dusk and are collecting everything that can bring them together faster.
