Lin Wei was thinking to herself that Jiang Su likely hadn't woken up yet since he had been awake at two in the morning.
As she was brushing her teeth, she contemplated whether she should wake him up and bring him along to school.
After brushing her teeth, Lin Wei changed her mind; what difference did it make if she woke him up? He'd probably doze off at school, it would be best for him to have a comfortable sleep at home.

She could just say that the top student was sick – her absence from last night's self-study class was because she was taking him to the hospital.
Lin Wei sighed, thinking how quite considerate she was.
