She does not want to talk to "Little Five". She needs the contact info to threaghten her, or to sue her.
Certainly "Little Five" does not want to talk to her. Then she push "Little Five" 's lover to give up her contact info, or she will tell their immoral relationship. What a terrible person, leverage her own sister's private life to reach her objectives ! Thanks god, she only exists in wenxuecity.
