While Creamy Mami does her thing in the studio, Megumi wonders when the next vacation will be when Shingo's father signals an interest in returning to Japan to celebrate Shingo's birthday and address his poor marriage prospects. Megumi inquires the nature of the phone call in an attempt to help Shingo define the imbroglio he faces before leaving a »Stop being so obtuse!!!« slap across the chops as a parting gift. While Megumi computes how to wield Toshio in her counterstrike subterfuge against Mami and curry Governor Tachibana's favor in the hope of marrying Shingo, Yuu is making time with Toshio when she strikes it rich in a lottery to secure a pair of amusement park tickets; for Yuu, the circumstances involuntarily force her into an encounter with the resentful Toshio who decided for the party after she mistakenly lashed out at him. This along with Shingo and Megumi's adversarial subterfuge ultimately ignites a three-ring circus that becomes the ironic evening entertainment much to Snake Joe's delight; while Megumi tries to salvage the damaged first impression, Toshio sees the light as he leads Yuu through the park.
