Jun kept her promise and really dragged Shi Su to the hospital.
Shi Su, of course, didn't have a fever, but she did indeed need a follow-up at the hospital in the past few days.
The doctor who came to her home for a checkup didn't have professional equipment to assess her recovery. After the follow-up at the hospital, the doctor suggested that since her neck could move slightly now, she should stay in the hospital and use professional rehabilitation machines to promote recovery. This would ensure her neck wouldn't be injured again when she joins the crew next week.
Just like that, Shi Su was inexplicably pinned down by Jun in the hospital, and they even got her a private room, asking her to stay for observation and rehabilitation for two days as per the doctor's advice.
Staying in the hospital has its rituals too. The nurse brought her a new set of patient clothes, and when Jun saw Shi Su in those clothes, she quickly took a couple of photos with her phone.
