DB Vol 7 Part 2

The Alpha teams didn't respond to a word he said from the very beginning. However, Seong-hyeon's frustration was limited to these outbursts. As soon as they arrived at the safe house, the people who claimed to have come to rescue him tied his limbs as if he were a hostage. They claimed it was to prevent any unexpected situations.
