The sex scene opens with Yuyu, a young man in his mid-thirties, flirting with a young woman in her mid-20s. The young woman, who has just returned from a trip to Europe, asks Yuyu if he's talking about her. Yuyu says no, but the young man continues to flirt with the woman. The woman, however, doesn't seem to be having much of a time flirting with the man. She's all, "Hey, I'm going to have sex with you tomorrow." The young man, who's been flirting with her for a while now, is shocked and confused. He's not sure what's going on, but he can't help but notice that the young woman seems to be getting a little nervous. He asks her if she's having sex with him, and she says no. He tells her to get some sleep, and they continue to flirt.
