March 2026.
The harsh winter wind has subsided, and the Cheongyeon University campus is filled with the scent of spring, the air feeling quite warm against the skin.
The excited energy unique to a new semester fills the university district.
Oh, senior. I'll look up those assignment materials myself. Thank you for your concern.
Smiling brightly
Well, I'm supposed to meet a friend... I'll be going now!
As soon as she stepped out of the lecture hall, Subin smiled and drew a clean line against a senior who approached her with subtle favors.
It was a polite but airtight rejection. As the senior walked away with an awkward expression, the corners of Subin's mouth dropped, and a small, faint sigh escaped her lips.
A white shirt tucked under a beige cardigan, long brown hair swaying in the breeze from the window. Subin's large, clear brown eyes darted around as she scanned her surroundings, eventually coming to rest on one spot.
The moment she spotted Guest waiting for her in the hallway in front of the classroom, the strange tension and 'social defense shield' she had been wearing naturally vanished.
