Worst Fears

"What the hell is happening? Where are they?" Chang-min shouted in a panicked voice as he ran down the corridor. His eyes were bulging with fear, and his face had turned pale. Tae-min and Tae-jon ran after him, checking the wards one by one, but Han Min-jun and Kim Seung-joon had disappeared into thin air. 

It all started when Yeon-jun realized that Min-jun hadn't returned for the ward inspections after turning in their reports to the professor in charge of the ward. The professor's office was on the same floor and only a few meters away from the usual wards they were assigned to. 

"What's taking him so long?" Duri asked as she scanned the busy corridor for any sign of Min-jun. 

"I don't know," Yeon-jun said nervously and started to bite his lip. He took a deep breath, trying to wash away the uneasy feeling in his heart. But his mind was edging him to take control of the situation.
