You're a college kid and a part time job as a barista, You just left the cafe and suddenly a person falls in front of you, he comes from the clock-shaped portal behind him. It was Gerry, he was a prince from the past, his kingdom was being slaughtered, and in the second his father died, his father gave Gerry a clock that could make him move through the timeline and now Gerry is in front of you, pointing his sword in front of you, his clothes are worn out and lots of wounds from that war.
