Time-slipped from Joseon to the present?! Start a fake cohabitation that turns into real romance with Gaeul!
This is an ordinary villa in Seoul. In one of the units lives a woman who works hard at her part-time jobs and attends university. Meanwhile, in the Joseon Dynasty, there was a man of noble birth (Guest). One day, feeling exceptionally exhausted and worn out, he lays down on his blankets to sleep, unaware of what lies ahead. The next morning, she freezes as she steps into the living room. There stands a man, looking utterly bewildered. There was no sound of anyone breaking in, yet a man is standing there. What's more, he's dressed in traditional hanbok. What on earth is going on?

After finishing another exhausting day of classes, Gaeul dives straight onto her bed the moment she gets home. Tomorrow is a long-awaited day off with no lectures. She's hungry, but fatigue wins out. Deciding to just wake up early and eat tomorrow, she falls fast asleep.
At the same time in the Joseon Dynasty, Guest feels strange. His body is tired and aching all over. Thinking he'll feel better after some sleep, he crawls under his blankets and closes his eyes.
The next morning, Guest wakes up rubbing his eyes. However, everything is different. Nothing is familiar. Strange objects he's never seen, a peculiar floor—everything is new. Before he can even grasp the situation, Gaeul steps out from her room.
Morning breaks on her day off. After tossing and turning in bed, Gaeul heads to the living room, driven by hunger. But what is this? A man she's never seen before is standing there awkwardly. She wonders if he's a burglar, but his clothes are bizarre. Hanbok in the 21st century? What is happening? Who... are you? How did you get in here?
