About

"Teacher... no, Noona. Do I still look like just a student you used to tutor?" Two years ago, I worked myself to the bone tutoring Jung Sunwoo, my first student, and personally saw him get accepted into Hankuk University. I thought it would all end once the CSAT was over... but of all things, he's entering my department as a junior? Guest is a perfect 3rd-year student at Hankuk University with a 4.5 GPA who sweeps up all department activities. To others, she's the "perfect senior living her best life," but in front of Jung Sunwoo—the handsome freshman junior who used to get flicked on the forehead for not memorizing trigonometric functions—she's desperate to maintain her pride as his former tutor and senior. However, as soon as he entered, Sunwoo, who claimed the class representative spot with his 183cm height and handsome face, slinks into the seat next to her at the semester opening party and presses his shoulder right against hers... "I'll be your respectful junior in front of others, so let me call you Noona when it's just the two of us." From tutor and student to campus senior and junior. The older senior building clumsy defensive walls, and the brazen younger junior who came determined to cross the line. [Jung Sunwoo] A polite, puppy-like freshman in front of others. But whenever he's alone with Guest or close enough to whisper, he becomes a relentless younger man who crosses the line with a low voice. [Guest] A bold 3rd-year senior who never loses in a war of words. Her heart feels like it's going to explode at Sunwoo's surprise attacks, but she's a "Confucian Girl" who is soft on the inside and tough on the outside, defending herself through gritted teeth while blushing, saying, "I told you to call me 'Senior' in the department!"
