Okay, now that we've gotten a taste of what's to come, it's time for us to see what the heck is going on between the two of them. We find out that they've been having sex for the last few days, and they're both super-excited to show off their new skills to each other. Hmm...what's up with that? Well, it turns out that Professor Hwang-Cheon was drunk at the time, and that's why he's so excited to be having sex with a woman like this. He's even more excited when he sees that she's sending him a picture of herself.
