In the art room, the two girls talk about their childhood together. They're both brothers and sisters, and they've been secretly following each other ever since they were little. When they heard that they were going to study abroad, they didn't tell each other about it, but now that they're older, they want to keep the secret. They don't think it's a good idea for her to ruin their relationship with their imagined feelings, so they tell her that she's the only girl in the secret camp and that she shouldn't ruin the relationship with her imagined feelings. They also tell her about how quan shang was in love with some guy, but her family didn' t approve of the man, and that's why she went crazy. They both think that maybe she was torturing herself and torturing herself, and then she also tortured them.
