Worried that he's about to lose money gambling with his boss, nana asks him if he'd like to gamble with her. Ooh, that's a good idea, says nana. He's going to play with her because she's so eager to gamble. Worried, he asks her what she would like to do with the money. She tells him to play some gambling games, like mahjong orpai gow. Confused, he says he doesn't know which one to play, but he does know that he loves coin flip. He asks nana if they're trying to save him from gambling, and she says that they only have two possible outcomes. The first is that they'll have to play a coin flip, and the second is that nana and nan will be able to play two sides of a coin, which is the most straightforward ward game.
