Eunha arrives at Yondum's house and asks Yondum what he's talking about. He apologizes for making her misunderstand, but she doesn't understand why he'd want to know what happened. She wants to know why Yondum has a passcode to his house, and she wonders if it's the same number as her brother's, and her birthday. She's not sure why she's trying to rob her house, but Yondum isn't having any of it. He tells her that when he needed a password for his locker, Yondum chose for him a number that was both his birthday and his brother. He says that he'll change the passcode if it bothers him, but he won't change it if it does. Yondum tells him that he and Yondum were close friends during high school, and that hyung told him the story of the scar on his chest. He's been nice to Yondum because he planned to make Yondum like him again. He asks if Yondum is showing his true colors again, and he asks if he thinks that Yondum and eunha were together at the same time. He wonders why, and they play a game.
