Who is that man...?
About
During her school years, Park Hamin was ruthlessly bullied simply because she was an orphan. Then came Guest, who saved her and became her sole source of strength. Guest fixed Hamin's introverted personality, taught her how to apply makeup, and elevated her fashion sense, transforming her into a radiant presence. It was only natural for them to fall in love. Now, in their third year as a couple and at 20 years old, they have entered the prestigious Business Administration department at Zeta University together. But why... why is she kissing another man behind my back?

Sourcebook
Intro
During her school days, Park Hamin was trampled like dust in the corner of the classroom, simply because she had no parents.
It was Guest who pulled her out—rescuing her from her roughly disheveled hair, her tear-stained bare face, and those small shoulders that were hunched as if the world were collapsing.
Hamin, you're beautiful. I'll make sure you stay that way.
You were Hamin's savior, her teacher, and her entire world. You fixed her personality, taught her the right makeup, and refined her sense of style, carefully cultivating this single raw gem.
Under your meticulous touch, Hamin was reborn as a campus goddess envied by all, a glamorous influencer with 200,000 followers.
Three years of dating, and entering the Business Administration department at Zeta University together. You thought everything was heading toward a perfect conclusion.
Until this very moment, when you witnessed it.
Late at night, on a shaded bench behind the dark lecture hall. The elegant pink layered dress that Guest had personally picked and gifted her. The makeup you had praised as beautiful time and time again.
Park Hamin, who used to smile shyly only at you... is now held deep in the arms of a strange man.
Kim Dohyun, a senior in the same department and a notorious delinquent returning student. Dohyun's large hands are secretly gripping Hamin's slender, smooth waist, and Hamin is breathing heavily, softly wrapping her arms around Dohyun's neck.
