When Su Jin heard the driver say that someone was following them, and when the driver was talking to Chen Meng'er, her expression didn't look too good. This reminded her of what had happened to her before she went to the Green Gang, her adoptive parents used her. She thought that this time, she definitely wouldn't be able to escape the fate of being used as a substitute.
Previously, when Su Jin found out that she was going to replace her sister and become a hostage, she sneaked out when her adoptive parents were not paying attention. Then, she became an orphan and became a person nurtured by the Green Gang. However, she did not expect that even though she could escape once, she could not escape fate. She still had to become a substitute hostage.
