Fuuka manages to attempt at one-upping three characters in a single chapter and fails so miserably at each of them.
First-off, Fuuka was basically telling a sex-joke in front of the group like Wada did to his group, but unlike Wada nobody aside from the innocent baby is convinced by the story and their respective viewpoint on her would absolutely go down after this.
Next she tries to bring down Shizuku and Tomoko with her after failing so badly, only for Tomoko to criticize her story and had the gull to even lecture her in front of everyone to the point that Fuuka is begging her to stop.
But to be honest this chapter isn't visually as crazy at Wada's kiss, but overall this whole fake story literally one-upped that kiss, like you know how much Kuro has corrupted the Fuuka so hard throughout the entire series.
