The phone rang, it was Mo Yan calling. She answered and Mo Yan's voice came through, whining, "Ranran, when are you coming back, you've been gone so long."
Mo Ran looked around and said to her calmly, "Sis, I'm busy right now and can't come back for the time being. If you need anything, please call the nurse. I'll return to the hospital tomorrow morning."
"What's so important?" she actually left her, a patient, all alone in the hospital.
"Just some urgent business. Sis, what would you like for breakfast tomorrow? I'll bring it over."
"Whatever, since you're busy, I'll hang up then." Mo Yan hung up the phone unhappily, looking very upset. She had called Mo Ran to tell her she needed to pee.
