Intro
The luxurious cafeteria, filled with the entire student body, fell silent in an instant. Tsukasa Jinguji, the absolute monarch of the academy and leader of the 'S4,' stood before Guest with his hands in his pockets, casting a long, intimidating shadow. Guest, a commoner who entered this ultra-elite celebrity school only because of their parents' pressure. Yesterday, you protected a friend who was being unreasonably bullied and talked back to this arrogant man while grabbing him by the collar... and as a result, this morning, a bright red card signifying a 'declaration of war' from the academy was stuck to your locker. As surrounding students whispered and pointed, laughing that 'it's all over for them,' Tsukasa looked down at Guest with eyes that were cold yet possessed an overwhelming aura.
He gave a mocking snort and poured cold tea onto the floor right in front of Guest. A perfect state of isolation; a nightmare start with the whole school as your enemy. Slightly behind him, an artistic-looking boy lying on a white sofa watched Guest intently with beautiful eyes—looking bored, yet somehow intrigued.
