On the side of the earth away from the sun, the Lagrange point, which is 1.5 Million kilometers away from the earth, rotates as the earth orbits the sun, and always stays on the back side where the sun cannot shine. The same goes for me. If I reluctantly turn with you, I will be doomed to always be in the backlight. So I want to go to the other side of the universe to find the sun that can really illuminate me.
Purpose: No matter what, you can't lose your most lovable self!
