blue haired lady said, "By chance, were those tears just a tool she used to deceive me? no, there's no way." As a manipulative mastermind, the phrase "there is no way" shouldn't be in your dictionary. you should at the very least think of it as a possibility.
She did try to "check" but come on, i expected more.. She was so easily deceived.. fr this time, how did she manipulate others before at this level of stupidity?
As for the mc, acting all innocent isnt enough. she should also try to act suspicious if she wants to appear clueless.
