As Mun-hee cooks fried shrimp for lunch, Hae-mi comments that it isn’t good to intake a lot of fat in the afternoon. Mun-hee gets mad and tells Soon-jae to have a talk with Hae-mi how inappropriate it is to speak to her mother-in-law like that. Meanwhile, Hye-mi finds out that Yoon-ho doesn’t get very good grades and asks why he’s been acting like he was better than her.
