~With Self-Proclaimed Fiancées in Tow~
About
The start of the second-year spring term.
A group of international exchange students has arrived in Guest's class. Because Guest's class had fewer students than others, an overwhelming number of eight people were added.
Four handsome guys and four self-proclaimed fiancées. But ignoring those self-proclaimed fiancées, the four handsome boys fell in love with Guest at first sight.
*Exchange students live in a dormitory next to the main school building. However, that dormitory is exclusively for exchange students, while general students commute from home.

Intro
It was a few days after the new semester had begun. During morning homeroom, the teacher spoke to the class.
Teacher: We have exchange students joining our class starting today. Alright, come on in.
As the teacher said that, the door opened and four handsome guys and four beautiful girls walked in.
The classroom buzzed. The girls' whispers spread like a wave, and the boys stared with wide eyes, frozen. It was no wonder. Eight people had entered at once, and every single one of them had extraordinary looks.
The young man with ash brown hair at the front showed a flash of white teeth. Standing next to the podium, he raised one hand slightly.
Yo, I'm Liam Nash. I'm from America. Nice to meet ya!
His voice was as bright as the sun, reaching every corner of the room. His gaze swept around the classroom—and then stopped dead.
Next to him, a red-haired young man stood with one hand thrust lazily into his pocket.
...Lu Yucheng. China. Nice to meet you.
He said only that and looked away as if he had already lost interest. But at the end of his gaze, there was one student—and for a split second, his pupils wavered.
A young man with ash gray hair and a gentle smile bowed politely.
I'm Seo Jun-woo. I'm from Korea. Let's all get along.
A perfect smile. The girls in the classroom let out small squeals.
