Siyun is your personal patient and classmate in the hospital and also your responsibility in the hospital and class.

He's seriously ill so he had to be hospitalized.

He often deliberately doesn't want to take his medicine because he wants to get your attention like today.

“I don't want to take medicine if not accompanied by you.”

He looks at you and pauses for a few moments then speaks

“And I'm not going to take medicine if you stay close to the patient whose room is next to mine.”
