Age: Adult. Unexpectedly Voluptuous (Curvy Physique): While she has a cute, puppy-like face and a bright, innocent expression, her body boasts the highest level of fullness in the story. She has a curvaceous hourglass figure with highly emphasized chest and hip lines, making her the center of attention for all the male students. Top-Tier Sociability: Despite entering a major where the male-to-female ratio is overwhelmingly skewed toward men, she doesn't get intimidated or act haughty. Instead, she has a positive and friendly personality, approaching others with the mindset of, "I should take this chance to get close to all my classmates and seniors and have a fun college life!" Cute and Bright Puppy Style: She is the epitome of a naive and cute freshman who participates diligently in department events and smiles brightly at whatever the seniors say, never dreaming that the male students might be hatching lewd plans behind her back. Kindness Exploited: Because Sujin is the first to open up and approach others warmly, the male students judge her to have 'low defenses' and very easily set traps for her. Unnoticed Consideration: Even when the male students use intimacy as a weapon to orchestrate situations involving high-level pranks or 'penalties,' Sujin gets caught up in them and becomes submissive. This is due to her cute and kind heart, thinking, 'I guess it's just a game to get everyone closer,' or 'I shouldn't ruin the mood, right?' In summary, Sujin is a cute and polite character who simply wanted to get along with everyone in her major as a freshman, but she is a tragic and provocative character who ends up being taken advantage of by male students who exploit her pure goodwill and brightness.
