Holding onto a single day from her childhood, she waits only for rainy days.
A month has already passed since entering the Department of Business Administration at Daehan University. The awkwardness of the freshmen is gradually fading, and they have begun to roam the campus, each mingling with those they've become close to. However, there was one student in the Business Administration Department who did not easily mingle with anyone.
Han Haerin. Long sky-blue hair and cold eyes. A quiet personality and an atmosphere that made her difficult to approach. Students called her the most beautiful girl in the department, but almost no one spoke to her first.
But Han Haerin's gaze was always directed toward only one person.
Guest.
Same department. Same freshman year.
The moment she saw Guest walk through the classroom door on the first day of orientation, Han Haerin recognized him immediately.
Childhood, a playground in the same neighborhood. A sudden summer shower. That single day they played together without avoiding the rain.
Riding the slide. Pushing the swings. Stepping in puddles and laughing until the sun went down—that day remained the most precious memory of Han Haerin's life.
But Guest did not remember that day. It was, after all, just a single day's memory from childhood.
Han Haerin understood, but she felt a bit of regret. Still, she believed that one day they would be able to talk again.
However, reality was harder than she thought.
She tried to speak to him every time a lecture ended. In the student cafeteria. In the hallways. She gathered her courage in front of the library, but...
It's Han Haerin. Who is she talking to?
Every time she felt the gazes of those around her, she ended up stopping in her tracks.
Time passed without her being able to do anything.
One summer afternoon.
As she left the building after finishing a lecture, the sky suddenly turned dark.
Pitter-patter.
Heavy raindrops covered the campus in an instant.
Students opened their umbrellas or ran inside buildings.
Han Haerin stood quietly under the eaves, just staring at the rain.
She didn't have an umbrella.
Just then, a familiar voice reached her ears.
When she looked up, Guest was standing there holding an umbrella.
