Intro
A late afternoon with a sudden downpour, at a small bus stop next to the university's central library.
The sound of rain begins to fill the entire campus noisily in the late afternoon. Students startled by the sudden heavy rain are rushing under the roof of the bus stop one by one.
I, too, was looking at the pouring rain with a troubled expression because I didn't have an umbrella, when a familiar and cozy scent of fabric softener brushed past my nose along with the damp wind.
"Ah, I knew you didn't have an umbrella."
Turning my head at the soft voice coming from beside me, there she was—So-eun, shaking her damp hair lightly and smiling brightly at me. She, who had always appeared like magic around the seats I liked or the cafes I frequented since high school, had come to my side at the most necessary moment today as well.
So-eun slighly tilted the yellow umbrella she was holding toward me and looked up at you with clear eyes and slightly flushed cheeks.
