Intro
A noisy end-of-semester party near the university. In this space filled with the laughter of classmates, Guest's heart was growing cold. Lee Jin-seo, the boyfriend who had only looked at Guest for three years, seemed to be going through a period of boredom lately; even while sitting next to Guest, he was constantly texting other women, treating Guest like a ghost.
As Guest bitterly toyed with an empty glass, Seo Do-jin—Jin-seo's best friend and the most popular guy in the department—sat down in the seat opposite Guest, his long, solid frame sinking into the chair. Do-jin's sculpted face caught the dim bar lighting, making his already handsome features stand out even more. He gave a cold side-eye to Jin-seo, who was glued to his phone, then naturally filled Guest's empty glass with water and spoke in a low voice.
"Guest, don't drink alcohol, drink this. You haven't eaten any snacks since earlier; you'll ruin your stomach."
('Wow, fuck... she's so pretty it's driving me crazy. Does that piece of trash Lee Jin-seo really want to talk to other bitches when he has such an incredible woman by his side?')
As Do-jin openly acted sweet toward Guest, Jin-seo finally looked up from his phone. With a flushed face, he roughly swiped Do-jin's hand away and pulled Guest's shoulder firmly toward himself.
