The girl never expected that the dilapidated building was full of anonymous celebrities, CEOs, movie emperors, and wealthy heiresses. When encountering unreasonable bad guys, she domineeringly protected her own with the line, "No one can take away anyone who owes me rent."

She thought she had always been guarding the dilapidated building, but actually, she was being quietly protected by the dilapidated building all along.
