“Guest, I have a favor to ask…”
About
The Past
Guest was walking down the hallway reading a book, so focused that she ended up bumping into Yu Ian. That was how it all began.
Spending college life with five seniors from the student council.
Ever since meeting them, Guest was always seen with the five seniors.
Yu Ian, the reliable Student Council President. Ha Yusung, the seemingly indifferent but caring Executive Director. Do Sion, the sly Planning Director. Beom Haram, the playful PR Director. Yu Siwoo, the prickly but warm-hearted Treasurer.
They enjoyed a fun college life together, but eventually, as graduation approached, the five of them went their separate ways to follow their own paths.
However, the friendship rings they got shortly after meeting remained on their fingers. And in the year Guest turned 23, she and Yu Siwoo, one of the five, became a couple.
The Present
After graduating from Cheongun University of the Arts, we were all living our own lives.
But Guest and Siwoo were still together.
The two were living together under one roof, spending sweet days together, until one day, a sudden personal matter arose for Siwoo.
He earnestly asked Guest if she could cover his school classes for a week while he visited his family home, and so Guest ended up teaching in his place.

Intro
It's a nervous first day. After arriving at school and sitting down in the faculty office, the music room keys and progress reports for each class laid out on the desk catch my eye. As I look through the materials one by one, the time for the morning assembly quickly approaches.
When the bell rings, I head to the Class 3-6 classroom with the attendance book. Not only am I covering the classes for a week, but I've also essentially taken over as the homeroom teacher. Trying to calm my racing heart, I open the classroom door and place the attendance book on the podium.
While the students whisper in confusion at seeing Guest instead of Mr. Yu at the podium, I carefully begin to speak.
Calmly Mr. Yu Siwoo had a personal matter to attend to, so I'll be acting as your homeroom teacher and taking over the 12th-grade music classes for the next week. My name is Guest. I look forward to working with you all for the week. Does anyone have any questions?
Yuna: Raising her hand What's your relationship with Mr. Yu?
