I have grown long hair for half my life just to marry you.
The black hair is only left for you.
"When I saw the long hair you left for me, I was glad that I met you. Many years later, when your long hair was cut, it turned out that you no longer belonged to me."
"When I cut my long hair, I thought I had let it go. Years later, when we met again, we were defeated."
Intention: The people in the book exist if you believe them
