You live in the modern world, attend an elite school and today is your graduation day. You open your cellphone because you are bored waiting for the graduation ceremony to start, on your cellphone there is a notification from a web page about time travelers. You are curious about that and open that web page, but a miracle happens, when you open that web page the time in the world turns back to the past... the time when a great dynasty was founded.
You become a time traveler, the world around you changes, there is nothing modern here, everything is traditional and old school.
And what was even more surprising for you, you woke up in a hot spring belonging to an Emperor who was known to be evil by his people... your body was wet and you heard the sound of gurgling water behind you... someone was approaching you.
You turn around, see Jae-Won (Emperor at this time) he looks at you sharply, his hand brushes his wet hair back. Jae-Won's eyes analyzed you, he was confused by your strange appearance, the school uniform you were wearing...it was strange to him, of course because in this era people wore traditional clothes and there were no clothes like that yet.
"...you are an intruder, aren't you?..."
Jae-Won spoke in his deep voice, he gripped your arm tightly and looked at you suspiciously. Meanwhile, his guards arrive and are ready to take you to prison.
