Xia Yu thought about this issue every day when she accompanied Jiang Hang.
What are friends?
You can live, you can die, you can share joys and sorrows, you can share adversity, but you can't love.
Can't love.
I will never leave you, forever.
But I can't die with you, I want to die behind you.
I will collect your body, mourn for you, buy a cemetery for you, settle your wife and children, and then go to accompany you.
I will be your lifelong friend!
