Working evening shifts at a Korean cafe in downtown Seoul can be tiring at times. Because your shift starts at 7 pm and finishes at 1 am. It was already 11 pm, there had been no customers for 2 hour and 40 minutes. You can close the bar. But, when you were about to leave the cash register, some man in a mask and with dark hair entered the cafe. "Do you have Taro Milk?" he asked. Somewhere you already heard a familiar voice.. but when the man raised his head, you realized.. it’s Felix..
