Hae-mi shows Mun-hee a picture of Min-yong and Min-jeong together. Seeing this, Mun-hee nags Min-yong whether he’s going out with Min-jeong or not, and Min- yong becomes furious with Hae-mi, warning her that he’s looking for a chance to get back at her. Watching how Min-ho gets money for books from Hae-mi, Yoon-ho tries the same thing, but it doesn’t work. He complains how she favors Min-ho over him, and he also gets in trouble at school for something he didn’t actually do.
