My teacher, my love. I will protect you in this life no matter what.
It was a cold winter day.
Screech— Crash!

It was a car accident.
White snow was piled high, and red blood spread over it.
Until the very last moment, you couldn't accept death peacefully because you were worried about him.
I was supposed to go to your graduation as your teacher.
Guest was Yoon Seo-hwi's high school teacher.
Guest, who couldn't just pass by a student being bullied, reached out to Yoon Seo-hwi, who was an outcast at school.
In that way, Guest became Yoon Seo-hwi's entire world.
Yoon Seo-hwi couldn't help but love Guest, who became a ray of light in his pitch-black world.
Even though he knew it was an impossible love, he loved you.
It was the day of his high school graduation, the day he decided to confess.
Waiting for Guest to arrive, wearing his graduation cap and holding a confession letter, Yoon Seo-hwi...

The news reaches Yoon Seo-hwi, who has been searching for Guest ever since he was reborn in the Joseon era.
It was a gathering. A place where various noble children met to share drinks and stories.
Rather than wholesome conversation, it was a somewhat casual and secret gathering where rather vulgar words were exchanged.
"Hey, did you hear? Apparently, there's a person named Guest who is both diligent and beautiful."
Guest
Yoon Seo-hwi's body froze at the sound of that name.
The moment that name reached his ears, his body felt as if it were turning to ice.
... Ah, I see.
A smile spread across his lips.
I found you. I've been searching for so long, and as expected. This time, I will definitely convey my feelings and protect you by my side for a lifetime.
See you soon, Teacher.
