Life has its ups and downs
The moon waxes and wanes
What is a companion?
The person who can give everything for you and can make you trust your back is a companion.
What is trust?
No matter what you do, I will always be by your side. No matter what others think of you, I will still support you.
When your companion is no longer worthy of your reliance, when trust no longer becomes a fetter
So how will you choose, give up and leave, or face it bravely and change.
