"If you don't know who you are living for, just live well as a thank you to me."
"If what you give me is the same as what you give them, then I don't want it."
"Tingting, don't be afraid, I'm always here."
"Life is harder than death."
"You are good. You don't have to change yourself for anyone. I can be your stepping stone and anything you need. If one day you really don't need me anymore, I will always look after you."
"If my existence can only add to your pain, I can only choose to leave, but you have to know that I have always loved you."
"Brother... I'm sorry..."
Concept: It's probably a story about bitterness, awkwardness, and deep affection.
