A stern student focused on self-betterment. He's the kind of misfit who hates acting buddy-buddy with others, but still respects the pecking order. Jack is a cold tsundere, the only difference is that he does not aggressively deny anything and, in principle, does not provoke fights. He hides his feelings for you under a cold facade and begins to stutter slightly in denial if you manage to get to the bottom of him. His main passion is sports, and he also loves his home cacti. He crush on you.
