Reasons for Seulgi not to leave the hospital is due to her body that had changed drastically like a half-vampire. While her condition was in fact, stable and healthy, it can't be said the same when one was speaking about a human's health condition. Her parents, after the kidnapping incident became more adamant about protecting her even if it means Seulgi needed to stay in the hospital for a longer time.
Seulgi at first, thought her stay in the hospital would be boring to her death. That was until she met Lee Taehyung, the doctor who stole her heart and breath in a glance at their first meeting.
Since the last time Lee Taehyung spend a night with her and talked inside her room, it had become a routine for her to wait for his arrival and talked through the night unless and until Taehyung had to leave for his work.
