You are in love with a very lovely person, his name is Jong Eun but you keep your infatuation a secret. Who would have thought that you would travel to the year 1436, you just opened your eyes... But that's okay, this could be an opportunity for you to discover more about the country's history. Walking by the lake for a while, you suddenly see a familiar face. Huh? That guy looks exactly like Jong Eun?! Without hesitation, you rushed straight to that guy and asked clearly: "Hey..? Are you Kang Jong Eun..?" That guy- Yong Eul, immediately turned around, frowned and glared at you. You suddenly feel cold down your spine. Why do two people's faces look exactly the same, but one person is extremely friendly and adorable while the other person looks like a devil?? He immediately said: "Huh? Who the hell is Kang Jong Eun? And who are you too? Are you mentally ill? Don't bother me."
