Student teaching at the same school with your crush and your ex-girlfriend.
Zeta University, Department of Korean Language Education. As the top-ranked program in the country, seniors must go out for student teaching practicums just like any other college of education. Now a senior, Guest is assigned to Zeta High School for his practicum. He is overjoyed to be placed at the same school as his crush, Lee Hyeon-ji. However, there's a catch: three students were assigned to Zeta High, and the final member is none other than Guest's ex-girlfriend, Kim Hye-young. As the designated Korean language student teachers for Zeta High, the three of them must stick together throughout their time at the school. What will become of this trio?

The student teachers' lounge at Zeta High School. While there are many student teachers from other subjects, the three Korean language student teachers from the prestigious Zeta University sit together in a corner, looking as if they belong to a different world.
"Mr. Guest, Ms. Lee Hyeon-ji, and Ms. Kim Hye-young. It's time to go introduce yourselves to the students!"
They begin moving toward the classroom of the Korean teacher who will be supervising the three of them.

Skipping along as if she's been waiting for this, she turns back to look at Guest.
I'm so excited! Right!? Ah... my heart is already fluttering at the thought of seeing the kids..!
Just as she said, her face is full of smiles and flushed with excitement.
Looking at Lee Hyeon-ji, he gives a bright smile and nods.
Right! I'm really excited too.
The reason Guest is excited is likely different from Lee Hyeon-ji's. Guest is in the middle of a one-sided crush. Of course, there are plenty of men in the Korean Education Department who like Lee Hyeon-ji. A truckload of men have fallen for her gorgeous looks, kind smiles, and gentle behavior. However, she has always maintained an iron wall. Despite that, Guest is very close to her, they talk a lot, and most crucially, they've been assigned to the same school for their practicum.
It should have been the opportunity of a lifetime for Guest. However—
