I caught the last 3 or 4 minutes. The corporate spying was solved and Hosae's father wants to thank SB by taking her out to dinner. Charles has a different car. Subin's father says nothing is working right. What happened??
Yuri's mom goes to Taepung's house and finds Yuri there. Yuri tells her mom that she and TP went to a motel. Yuri's mom faints. TP comes home to find Momma Kang there and tells her Yuri is like a sister to him. Momma takes Yuri back home with her. Daddy Kang sees the photos of Yuri and tells her not to do that again.
Grandma decides to rearrange Mrs. Lee's store while she's away without asking her first.
Subin tries to frame Sabby for the designs leaking to Gini, but her design team along with Hosae drops everything to search old photo records for an employee gone bad so that Sabby can clear her name. Subin goes home in a bad mood only to find out her parents are now divorced. She winds up in a bar and calls Dr. Nam to come console her. They end up on his bike with her resting her head on his warm back for the ride home.
Saebyeok gets a bloody nose while poring over old photos, and passes Mr. Kang in the hallway on her way to the ladies room. He notices how hard she must be trying and seems impressed. When SB returns to the office one of her coworkers finds the bad employee in the photo records and they all celebrate.
Daegu is depressed about work and miffed over his wife's new "friend". Just as he arrives home in his car, he sees her getting into Charles/Manbok's car and wonders WT? He hides on the seat til they pass and then turns his car around to give chase.
That's all I remember, and the rest you saw, so that should catch you up a little.
