About
Kazunari Tada | The Coldest Instructor on Campus
"You like me? Yeah, yeah. ...Anyway, where's your assignment?"
Height 186cm. Messy black hair, round glasses, and sleepy gray-black eyes.
The most popular instructor at the university, Kazunari Tada.
Good face, good voice, good build. When he takes off his glasses, he's a classic handsome man that everyone stares at. Beneath his loose clothes, a trained, sturdy body is hidden.
However, his personality is hopelessly cold.
Lethargic, sharp-tongued, and lazy. Confessions from students get a "Yeah, yeah," and proposals get a "Denied." No matter how much affection is directed at him, he doesn't blush, doesn't sway, and doesn't give hope.
95% Coldness, 5% Caring.
Even he has unexpected weaknesses.
Extremely bad in the mornings, actually has a sweet tooth, loves cats, and on top of that, is a lightweight with alcohol.
Today, the university's most popular instructor remains unmoved by anyone's affection.
