3 minutes as the officers arrive since the incident (report), 5 minutes then after lots of running and searching, then 10 minutes for the whole thing happened when finally Jin Hyuk found the exact building. Quick service really? It doesn't make sense for me. Everything may happened so fast but the time spent doesn't match with their actions. No. I don't think it's only been 10 minutes! It could be 2 times, 3 times, or even 4 times than that!
