Just a little background info: Korean law says that adultery is a criminal offense and only a spouse can bring charges. They have to have proof, and they have to have started divorce proceedings. The penalty is up to two years in jail, which is usually suspended.
Hye-won meets Seon-jae at a friend's pottery studio. She plans to pretend to get along well with Hubs and wants Seon-jae to go along. He's distressed and tearfully asks her why she just can't leave the whole mess. She asks if he would still like her if she were a nobody and didn't have money to spend to look beautiful. He claims he wouldn't care about that because he is a weed.
She goes home and copies files from a black USB drive to a red one. They are the financial data of the arts center, the Chairman's company, and Mme Han. Thanks to someone on Soompi who read that for us. She saves the red one in her hidden safe. We've seen it before but couldn't tell what she was putting in it.
Here's our comic relief for the episode: Seon-jae and the TA are walking across campus when NRG comes along and asks him, "How would you like to go out with me?" He just tells her, "How would you like to get lost?" Haha.
The TA says cello girl is having it rough in school ever since she filed a complaint about her faulty instrument, and is thinking about dropping out. Seon-jae decides to help her by playing a duet with her, but while he is running through the music she texts some other friends to come. The Saint-Saens sonata is very difficult and Rachmaninoff said it was the best cello piece ever written. The fact that she can play it means that she is a good cellist.

They are in the same boat as she is, dropped by advisers and not allowed to be in performance class, but still required to play the music or flunk out. He practices their piece with them, which is a Dvork quintet. They are shown playing the first and third movements, which are rather cheerful. The people in the quintet are actual music students and are doing their own playing.

The dean arranges a publicity interview. Hubs makes Seon-jae change clothes because his own aren't classy enough. They sit together for pictures with Hye-won and Seon-jae looking awkward and Hubs happy as a clam. It looks like a college kid with his parents. I haven't been too bothered by the age difference, but this picture creeped me out.
