I only have a couple of minutes right now, but I'll give you the general drift. Basically, as I remember it, both episodes covered similar ground. As you saw last week, Junho's horrible mom took Eunji home with her because she was sweating in the poor peoples' house. She informed Jiyeon of that after the fact. After Jiyeon got used to that idea and said she could spend a day or two there (she did not like it at all!!), from there they all went to the rich family's summer house. After Eunji cried for her mother, they made JY come out to the summer house--she took a taxi all the way there--and said she should stay with them for the weekend and go back to the city with them on Sunday.
JY would rather have taken Eunji back with her right then, but the little mite said she wanted to stay. It seems like Junho and JY are a bit friendlier now, esp because he is a very good father, but JY does not want to get back together and said so. At the end of the weekend, there was more tussling over where Eunji would go, but finally they let JY take the baby home, with the stipulation that they would send a helper over--their housekeeper--to spend days at JY's apartment.
Meantime, JY's partner and Mr Seo have to meet with her parents. Her father has heard about Mr Seo and wants to meet him. So they have to keep up the pretense that they are dating a while longer. Only now, her father wants them to set a date to have all the parents meet, I guess so the couple can get married! She is mortified and tells Mr Seo that they will have to come clean or tell her parents that they have broken up. He surprises her by saying, basically, "I don't know about you, but I haven't been faking. I really like you, and I'm going to go to the meeting with all the parents next week!"
That's all I remember right now. I don't think a lot else is happening, except that Taesop has gotten out of the hospital and still doesn't want to be around his mother. Also, his stepfather has found out from one of the sisters that Jiyeon was lying when she said she and Junho were getting back together.
