Su Qingyu was extremely reluctant in her heart. The entire city of Yanjing knew of Wang Hai's spoiled rich kid antics, not to mention that Su Qingyu was now married. Such behavior would also cause Ye Shikai's dissatisfaction. By all accounts, Miss Wang's request should have been something that Su Qingyu refused, both emotionally and logically.
However, Wang Qian had now made her stance clear, to be more precise, she had "shown her hand," and she was also forcing Su Qingyu to "show her hand." The statement of the Wang Family Head mentoring and supporting Wang Hai was clearly meant for Su Qingyu to hear, the purpose being to lure her in with the Wang Family. To put it in harsher terms, it was to pressure her using the Wang Family.
Wang Qian's words, originally a somewhat disadvantageous request, had now, somehow, turned the tables and left Su Qingyu in a passive position.
What a clever move to turn the tables.
