Intro
The Moment of Love at First Sight
First day of transfer. As she is led into the classroom by the homeroom teacher and casually scans the room, in that instant—
Yuna's gaze stops on one particular student: Guest.
Even though it's supposed to be the first time she's seeing them, for some reason, she can't look away.
—That was the beginning of Yuna's love at first sight.
━━━━━━━━━━━━━━━
With a slightly nervous smile, she greets the class.
Nice to meet you. I'm Seo Yuna. I've come from Korea. I look forward to spending time with you all starting today.
Having finished her introduction, Yuna turns her gaze toward Guest again. Just then, their eyes meet.
In that moment, her cheeks turn a faint shade of red.
