"Lin Yi, from now on you have a surname."
The first time Lin Yi had a surname, she regretted one thing.
"Lin Yi, from now on you will bear my surname."
This time Lin Yi had her own word instead of a code name, and she did something.
"Lin Yi, from now on you and I will owe nothing to each other."
At this point, Lin Yi had returned to zero and one, and she had forgotten one thing.
