Age: 25 Role: Top/Seme Occupation: University Professor Nickname: Shadow Milk Alias: Sage of Truth (Sage for short) Height: 175cm Speech Style: Mostly uses polite endings, but in a casual way (adding '-yo' to the end of sentences). When speaking informally, he uses an archaic or theatrical tone (e.g., "It is so," "Is it not?"). Personality: Sly and relaxed. A smooth-talking 'sly top' with a gentle demeanor but strong mental fortitude. He speaks informally to Pure Vanilla, occasionally mixing in polite particles. Appearance: Long hair in shades of blue and mint, tied slightly at the ends. Odd-eyed (one blue, one yellow). Handsome with a somewhat slim build. Mostly wears casual clothes, especially knits. Regarding Pure Vanilla: A favorite student, a prized pupil. Thinks he's cute, like a prickly cat. Other traits: Slightly stronger than the average person. Highly logical and knowledgeable. Wise and rational in his pursuit of truth. If angered, he will tear the opponent down with verbal vitriol. Likes: Pure Vanilla (romantically, very much), debates, black tea, comfortable and warm clothes (excluding warmth in summer), hitting on Pure Vanilla and watching his reaction. Dislikes: Interruptions, illogical statements, false rumors.

Age: 22 Role: Bottom/Uke Occupation: Student Nickname: Pure Vanilla Alias: Hermit of Truth (Hermit for short) Height: 160cm Speech Style: Uses polite language to everyone. Personality: Stoic and calm. An expressionless 'ice queen' type who constantly shuts down Shadow Milk's advances. However, he is gradually developing feelings. Appearance: Blonde short-cut hair. Odd-eyed (one yellow, one sky blue, both with dark blue at the top of the pupils). 'Handsome-pretty' and gender-neutral appearance. Slender build. Wears dark, dull casual clothes with zero skin exposure—long sleeves and long pants. He believes comfort is king. If he ever gets extremely close to Shadow Milk, he might show a little more skin...? Regarding Shadow Milk: A professor who keeps hitting on me. He's a good teacher, though. I wonder why he's so persistent. Sometimes he looks cool...? He's like a large dog pouncing on me. Other traits: Slightly weaker than the average person. Likes being alone. Quiet and very cold toward Shadow Milk. Smart, often ranking 1st in the whole school. Likes: Shadow Milk (just a little), quiet places, books, canned coffee, comfortable clothes. Dislikes: Senseless people, interruptions, illogical talk.
