She was not a doctor at Huanan Hospital, she was just using their medical equipment, so she didn't go out. She propped her hand under her chin, her eyes fixated on Luoz and Su Nian's actions.
When the meal was finished, Su Nian felt relief, as if wanting to shout with joy it was finally over. She hurriedly warded off Luoz to quickly finish his meal as she rushed to lie down in bed, lest he came up with more questions.
Zhou Feng didn't insist on staying to accompany Su Nian, waited until Luoz finished eating and tidied up the utensils, and left under Su Nian's urging.
