"Show me your phone!"
"No."
"Bring it quickly"...
"Isn't this my mobile phone number? I don't have this name. You pig-headed, Alzheimer's man, I am Chen Momo. Change it back quickly, this name is ugly and weird!"
Momo, do you know why I kept your name as a sign of regret?
…
I am reminding myself that if I lose you one day, I will definitely regret it!
