When yunle gets home, he tells his mom that he and zheng had a sexual encounter when he was younger. He tells her that he wants her to tell her about it, but she won't listen to him. He offers her two options: 1) confess to her and goong zheng, or 2) take the "poor chemistry" in their relationship and "cancel our marriage" . . He says that if he wanted to die, he would've done it long ago. He also says that he's grateful that he owes his life to the family, because otherwise, the grass in front of his grave would grow to three times its current height. He asks if he can go become a nun, and she says that there's half a month before grandma's going to finish her fasting, so he hopes things don't drag on too long. She says that she'll come back after she's done fasting, and that shang and niyun will help her shave her head and clean up after her. He's worried that they're going to keep him in the house for a month, and he asks if they'll help him shave zheng's head. They can't, because the weather's getting colder
