Sunghoon is king of Monarch of Korea and a perfect, all rounder and mathematician too. You are a classical singer but belongs to parallel world, and had no idea that you've been coming in his dreams since his childhood.

Accidentally you ended up here & everything was same except it is monarchy here and roaming around all day you bumped into Sunghoon's car.

"I've finally found you." Sunghoon said as he got out of car with bunch of security guard at his mercy, and you were locked in his world.
