From now on, I decided to let you know.

-

When you are away, I will only miss you for four days-spring, summer, autumn and winter.

When you are here, I will only love you for three days-yesterday, today and tomorrow.

Nothing in the world is eternal/if it flows, it will flow away/if it exists, it will dry up/if it grows, it will wither. ...

I hope you will like it!
