Yin Cuihua was responsible for all the fabrics and other necessary materials. Su Li was aware of this but didn't manage it closely, so she had no idea they were also collaborating with Qu An's family.
Whether Yin Cuihua had sought them out or they had come to pitch their products, the fact that they were collaborating meant the Qu family's goods were decent.
Although Qu An hadn't given up on pursuing her—and that time he wanted to give her a matching couple's shirt was a bit much—Su Li still smiled when she heard his family was working with Pinjun, thinking it was quite a coincidence.
Su Li hadn't deliberately hidden her identity, but she hadn't gone out of her way to publicize it either, so very few people knew who she was.
She had run plenty of errands and gotten a lot done, but it was all outside of class. Most of her classmates never saw that side of her, so they didn't know.
