"Sister-in-law, it's not that I don't want to help, but I really can't. You know, I'm very busy." What Chu Xiaoqiao meant by being busy wasn't about the store being busy, but the base being very busy.
She's not just minding the store here; she also has to think about how to improve various indicators at the base. She's quite useful, so she doesn't want to say much more, hoping her sister-in-law would understand.
"No matter how busy you are, you have to take care of your health first, so you won't regret it in the future." Qin Xue didn't want her to go on with her wild ways, which wasn't loving her but harming her.
As the elder sister-in-law, Qin Xue had the obligation to pull her back and couldn't let her live so nonchalantly.
Moreover, now it's possible to take care of her health. In the future, when she wants to get married, her body will be healthy, avoiding further issues.
