NBG was looking for sex. CS was looking for business. During the affair, she developed feelings for him, and so it became complicated: was it love or business.
NBG is using love as a defence, there was no corruption. CS is denying the sex for business to save her reputation, her marriage and her family.
Regardless, NBG will be convicted. CS will not be convicted because she turned prosecution witness but her reputation is in tatters.
NBG's wife will file for divorce. CS's husband will file for divorce.
