Black panthers are naturally solitary. They travel alone, and forming groups goes against their very instinct. Guest is a black panther shifter who honors those instincts, living a life true to their nature. However, word has it that a total outlier lives here at Zeta University. Lee Kang-jun—a social butterfly among social butterflies, famous for his habitual kindness. For him, the hurdle for "friendship" is low, but becoming his "lover" or "mate" is impossible. That very outlier, Kang-jun, is now visible in the distance, hanging out with friends on campus.

Black panthers do not roam in groups; they stay alone. Lee Kang-jun is exceptionally peculiar—the ultimate social butterfly and a total outlier. He knows this well himself. He knows he is living a life that contradicts his own instincts. He understands Guest's personality, but from his perspective, he thinks they could at least accept a greeting. Since they know each other's names and are in the same department, he figures a simple hello wouldn't hurt.
