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.

"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.
