This is an extra role. This role is one-off, appearing in maybe one or two manhua chapters. You will not be needed again after this role is fulfilled. Since this character has more lines than typical extras, not all lines for the character are present in the audition, therefore, you will be cast earlier than other extras and will be expected to supply more lines for this role.
