"Clan Leader! I'll tell you! I've been with Gu Chengyi for three or four years. It was he who promised me he would divorce his wife, and that's why I got involved with him. He even said he would give his mother-in-law some silver and divorce her sooner, then marry me. That's what he said. Otherwise, why would I get involved with him?"
Wang Yue figured that since Gu Chengyi was so shrewd, he certainly wouldn't make such a promise to her. On usual days, he would at most use some silver coins to coax her. Both were previously consensual in their relationship, each content in their situation.
Later, as Wang Yue and Gu Chengyi's encounters increased, she inevitably developed some negative intentions.
She also had a son. Her in-laws kicked both her and her son out, and the household relied entirely on her to exchange her body for some silver. If she could really be with Gu Chengyi, she wouldn't have to worry about future days.
