The class heads down to Tongyeong in buses, minus two boys whom we'll get to know separately. One of those two is HAN YI-AN (Nam Joo-hyuk), who's missing the trip because he's a swimming star and is at a national meet.
Eun-byul listens to a live sports broadcast as his race unfolds, and lights up when she hears that he's won. Her crush must be a secret, though, because she hides it from BFF Song-joo, even though it's no secret that they're friends.
Based on Yi-an's bashful text-flirting with Eun-byul, the crushing is mutual, and dates back to their kiddiehood. In a childhood flashback, we see young Eun-byul admiring Yi-an's swimming medals and asking for one of his many. He refuses but promises her the first medal he wins at the national level. She huffs that she doesn't believe he'd do that when he won't even give her a trivial medal like this one. Yi-an retorts that she's a dummy-he's not giving this one to herbecause it's trivial; as in, he'll give her one that's important. A-dor-able.
The high school minefield extends to the parents, and Eun-byul's mother does a favor for another mother by introducing her to an exclusive clique of moms. The leader barely hides her disdain for the newcomer (Shi-jin's mother), doling out some passive-aggressive barbs before deigning to give her card and number out.
The girls hear about Yi-an's gold medal, though Eun-byul plays it cool and doesn't show much excitement. She says that they grew up knowing everything about each other, as though Yi-an is nothing more than a sometimes-annoying buddy.
But then Eun-byul gets a text that darkens her mood immediately. It's from a girl named Jung Soo-in, and says, "Just because it's in the past doesn't mean it never happened." Eun-byul seizes up in shock-definitely scared, maybe even guilty.
So for the rest of the day, she's withdrawn and quiet, despite her friends' attempts to draw her out. When Song-joo prods her to talk or eat, she snaps and yells at her loudly, to everyone's surprise.
We hear a bit of the story from the school moms, who talk in vague terms about some incident last year involving Soo-in, who had moved away but is now apparently back. It must be a scandalous incident, because when the other moms recall that Soo-in and Eun-byul were friends, Eun-byul's mother is quick to say that no, they weren't really friends, just casual acquaintances.
As the school trip arrives in Tongyeong, we hop over to Eun-bi at Love's House. She assures a worried Ra-jin that she's okay despite not feeling well, and the little girl says that although unni is popular and has lots of friends at school, she only has unni. To comfort her, Eun-bi promises that she won't get sick anymore.
But while Love's House was at least a safe space for Eun-bi, today her tormentors show up for more bullying fun. Wearing beatific smiles, they explain to the director that they were concerned about Eun-bi, and that they wanted to help out by doing their community service project here.
Of course, once they're alone with Eun-bi, it's back to sneering and malevolent threats. The sidekicks are bad enough but it's leader So-young who drives the evil train here, telling Eun-bi to do their work since she's living off their parents' taxes.
Ra-jin witnesses the scene and looks upset to see her unni being pushed around. Eun-bi doesn't want to let her see the true situation either, so she lies and agrees with the bullies that this was all a fun joke, and she's fine.
It's clear that So-young sees her powerful father as a shield from any possible blowback, and even tells the orphanage director that her father is on a scholarship committee and would like to help out Love's House. Eun-bi sits there in nervous confusion, trying to see what her bully is getting at.
Meanwhile, the high school students settle into their hotel rooms, playing games and having fun. Eun-byul remains in her funk, and reads a clipping featuring Love's House with a photo of Eun-bi in it.
