"Tae-Tae, what was in this glass?"
Tae-min was taken aback when he heard Seung-joon call him "Tae-Tae" - a nickname he had never used before. Seung-joon had a strange expression on his face - his eyes were dilated, and he was grinning like a fool. Tae-min noticed the glass in Seung-joon's hand and suddenly felt a sense of dread. Throughout the evening, Tae-min had been keeping an eye on Min-jun, who had been drinking heavily. He had been so preoccupied with Min-jun that he had forgotten about Seung-joon. Tae-min broke out in a cold sweat as he realized what had happened.
