She then takes a taxi all the way BACK to school, thinking that Bam Bam is still there, waiting to walk back home with her. Seriously? You've known this guy way longer than me, and I can tell you there's not a chance in hell he's waiting there for you.
And yup, Bam Bam is sitting peacefully at home, until Mom asks why he came alone, when Nana is unfamiliar with these streets and there are crazy people about. Bam Bam remembers the trenchcoat pervert, and starts to get a little worried as he sits outside. Exclaiming how annoyed he is, he heads out.
Sure enough, Nana encounters the trenchcoat man on her way home. He's quite the bumbling flasher, and resorts to begging her to look, just once. Erm, gross, dude. Who's going to say yes to that? She loses her shoe in an attempt to get around him, so he picks up the shoe and takes off running.
She gives chase, wanting her precious gift from Bam Bam's mom back, so finally they strike a deal—he'll promise to give the shoe back if she promises to look, just once. And then, stupid girl that she is, agrees to it!
She asks for a moment to prepare, and Trenchcoat starts to unbutton his jacket...
...and just as opens up his coat to flash her, Bam Bam appears behind her, putting his hand over her eyes. He turns her around to face him. She's stunned when she realizes what's happening, as her heart starts to race.
Bam Bam gives chase and Trenchcoat instantly lands on his knees, begging not to be reported since he's new at this and has a family. He swears never to do it again. Seung-jo gets Nana's shoe back, and lets the man go.
He returns her shoe like a proper prince, and Nana asks if he came out to look for her, because he was worried. He claims it was to go to the convenience store. Nana: "But the timing was so perfect." Bam Bam: "That's just my bad luck." She smiles, and scurries behind him all the way home.
Bam Bam stays up late in an attempt to study, but can't get past the first pages of any of her books. Mom comes in with a late night snack, wanting to bond with her, so they look at baby pictures of her, and then Bam Bam.
Mom confesses to wanting a little girl so badly that she raised him like a girl when he was little, but then eventually had to fess up when they were found out at a community swimming pool. Bam Bam was apparently scarred from that as a child. Um....yeah, I should say so, Lady! She thinks that maybe this has something to do with why he's so cold now. She adds that he thinks all these pictures were burned, but she's still got the negatives, so she holds onto them. Nana smiles deviously to herself.
The next day at school she can't stop laughing over last night's discovery. Just then, Bam Bam appears in the doorway of her classroom, motioning for her to come out. With everyone looking on, he tells her to come outside with her gym clothes. She doesn't know what's up, but she complies, and realizes when she takes them out of her bag that their clothes have been switched.
With the entire class watching them from the window, they go outside and exchange gym clothes. Nana takes this opportunity to go in for the kill. Nana: "Why didn't you just wear them? You should be used to girls' clothes by now." And with that, she takes out the picture of him as a little girl.
All of a sudden his calm exterior disappears, as he frantically chases her up and down and around a tree, desperate to get that picture out of her hands. He finally pins her against the tree, at which Geumdal and Mark both freak out from their window. After much chasing, Nana finally tells him he can have the picture back, but at a price.
