My virgin mind has recently been violated by knowledge of what "butt chugging" is. Kids, you're going to be getting plenty of enemas in the latter part of your life. Why rush things? Preserve the sanctity of your rectum.
Kang San drives up and confronts a stunned Chang Hee, telling him about Gi Cheol attacking Hae Joo just now. San rebukes Chang Hee that if he's not man enough to defend his woman, then he should let her go. Chang Hee, still reeling from what the loan shark told him, breaks away from San and goes to home to face his father.
Hae Joo returns home, trying to act like everything is okay although her cheek is red (from the slap) and her clothes are a bit torn. Dal Soon's dirty mind immediately jumps to the idea that the two youngsters have been fooling around. Yet later she sees Hae Joo is upset.
When an angry Chang Hee comes home, Gi Cheol thinks its over the latest abusive act he perpetrated on Hae Joo. (There have been so many I can understand how he couldn't keep them all straight.) Chang Hee shows Gi Cheol the picture in the paper of the arrested loan shark and demands to know why his father would do such a thing to a little girl. Gi Cheol doesn't deny he told the loan shark to make Hae Joo disappear, but his excuse is he was worried Chang Hee wasn't concentrating on his studies for mooning over her. Quite frighteningly his father warns he's ready and able to do the same thing today if Chang Hee doesn't break up with her.
Chang Hee packs his bags and finally (Finally!) leaves the big house. He drives down to Hae Joo's house, but instead of going up to the door, he texts her to come out and meet him. Dal Soon, still worried about what's going on, orders sister Young Joo to basically follow Hae Joo and spy on her. Hae Joo asks how the interrogation of the loan shark went. Did he find out why the thugs did what they did to her family? Chang Hee changes the subject and asks her to run off with him and get married. He tells her San told him about Gi Cheol attacking her and so he's left his father. Saint Hae Joo urges him not to be so unfilial and to not abandon his father.
Young Joo returns with her report of Gi Cheol's attack. Sang Tae is his usual idiotic self. Dal Soon stews.
Saint Hae Joo refuses to abandon her (idiotic) family. She and Chang Hee argue and she walks away. She comes home to be confronted by her family. Dal Soon yells at her for not telling about the attack. Whereas before Mom was all for Hae Joo marrying into Chang Hee's family, now she's forbidding it.
We get a music video of our three leads all being miserable.
The next day at work, Hae Joo discovers the shipbuilding is going to be behind schedule because the production costs have been severely cut. She goes to ask Il Mun about this. He just tells her it's not part of her job to be concerned about this and runs her out of his office. We can tell from the dramatic music playing that Il Mun has something to hide.
Kang San has drinks with Lee Bong Hee. He flatters her up one side and down the other. She totally buys it. San then gets to the heart of the matter. He asks her just why Jang Do Hyun is so interested in drilling ships when everybody knows there are no domestic oil sites around Korea. Bong Hee brings up a name from the past. Has San ever heard of Dr. Yoon Hak Soo? (Hae Joo's murdered father. The first murdered father, not the second murdered father.)
Dal Soon goes up to the big house, kicks off her shoes, and proceeds to attack and bite Gi Cheol. (Pregnant Bitch Mom, I don't know how this happened, but suddenly you're my favorite character ever!) She tells him if he ever hurts Hae Joo again, she's going to break both his legs. As she's leaving, Dal Soon pulls out a bag of salt from her purse and starts throwing it around. (In Korean culture, salt wards off evil spirits.)
Just as Dal Soon starts to leave, Geum Hee sees her and invites her inside. (Inside the big house, where the Jang family live. Not the little big house where Gi Cheol lives.) Geum Hee apologizes for her visit back in Geoje. Dal Soon asks what happened to Geum Hee's lost child. She tells the story of how Park Gi Cheol accidentally (on purpose) dropped Yoo Jin in the ocean. Geum Hee goes on to explain how her daughter had a burn scar on the back of her neck just like Hae Joo. She also had a yellow knitted top like the one Dal Soon threw away, which explains why Geum Hee was asking the questions she was before.
Changing the subject, Geum Hee knows that Gi Cheol is opposing the marriage between his son and Hae Joo. Geum Hee offers to help straighten things out with him. Now that the marriage deal is off the table, at least in Dal Soon's mind, she gets all rude and tells Geum Hee not to stick her nose into other people's business.
Il Mun calls Kang San into his office for a meeting. Il Mun wants to build the ship with propellers made by another company. This is the exact opposite of what his dad wants to do. Do Hyun wants to build his own propeller here in Korea. San points this out to Il Mun. Il Mun claims the company doesn't have the funding or the technology to build propellers. Oh, and can San not mention this little private meeting between friends?
Yoon Jeong Woo and another prosecutor discuss their budding case against Il Mun for embezzlement and other stuff. Ah, so the production costs at the shipyard haven't been cut so much as Il Mun has been chopping off a big piece of the pie for himself.
Chang Hee drops by to visit with the Chun family. Dal Soon tears into him and throws him out (but not before Sang Tae hits him up for some money.)
Jang Do Hyun meets with Grandpa Dae Pyung. Do Hyun suggests they marry San with In Hwa and let bygones be bygones. Grandpa accuses him of using his own children to achieve business goals. Do Hyun brings up the stories he's heard about Kang San's parents, so it's not like Grandpa is so wonderful. (C'mon, tell us the stories! What is the deal with Kang San's parents??)
Chang Hee has pulled out the old file on Chun Hong Chul's accident. (Oh, is he suspicious?) He's interrupted by an urgent call from Do Hyun. Turns out that prosecutor from earlier, the one working with Jeong Woo, has gone and tattled to Do Hyun about Il Mun being in trouble. Now Do Hyun orders Chang Hee to put a stop to it any way he can.
At work, Hae Joo is in a meeting with the development team. There's some kind of talk about propellers that just makes me fade out of consciousness. The end result is Il Mun throws her out of the meeting for asking too many questions. A half drunk Kang San runs into her in the hallway and asks what's up. Hae Joo confides in him that she thinks something fishy is going on around here.
Chang Hee rushes into Jeong Woo's office and informs his boss how that other prosecutor is a spy. That Do Hyun knows all about Jeong Woo's case against Il Mun. Chang Hee advises Jeong Woo to drop Il Mun and instead go after Do Hyun.
Speaking of Do Hyun, he's brooding in his office when Nameless Minion (who hasn't changed a bit in 15 years) brings in a box. Do Hyun opens it to reveal the bent and bloodied license plate off of the truck that Gi Cheol used to hit Hong Chul. (How did they get a hold of the plate?) The two men discuss what the statute of limitations is on a murder case.
Dal Soon brings a packed lunch to Hae Joo down at her office. The two women go out to the seaside for lunch. Dal Soon realizes this is the first time she's ever packed Hae Joo's lunch. This causes the woman to start feeling guilty for all the times she's been so mean to our heroine over the years. Choked up with tears, Dal Soon confesses that she's not Hae Joo's birth mother. (Hae Joo already suspected this years ago so I don't understand what the big surprise is. But perhaps now she'll get to ask some questions about the past.)
