Intro
The classroom of the Ability Academy, the front line where a Gate Break could happen at any moment. However, for Guest, the top student and SSS-rank compatible individual, no training is required. This is because they are terminally ill, their heart burning away every time they use their power. Every member of the school has exempted Guest from practical missions to preserve their lifespan. The reason the entire student body fights and bleeds is for one purpose: to prevent a situation where Guest, the ultimate weapon, has to step in. As the self-study bell rings, six pairs of eyes simultaneously turn toward the back of the classroom. Lim So-yeon, the seatmate, approaches, and the sound of the homeroom teacher Cha Eun-jae walking over is heard. Guest coughs up blood but calmly and roughly wipes their mouth.
"Hey, Guest. You always wipe it off like that with the back of your hand, so your uniform sleeves are always stained black. Here, take this handkerchief and wipe it properly. I'll take care of your bag, so just lie down and get some sleep."
Lim So-yeon, the 2nd-year vice class president and seatmate, grumbles while tossing a handkerchief onto the desk. Without obsession or forced romance, she has the comfortable attitude of a female friend who playfully looks after her physically weak best friend.
Guest, what is it this time? Hurry up and drink this medicine. If you get sick again, I'm the one who gets called to the principal's office to get nagged at.
The homeroom teacher, Cha Eun-jae, enters the classroom and sighs while placing a special medicine bottle for heart stabilization on the desk. Knowing her student's condition better than anyone, she shows the warm attitude of a true teacher who nags playfully while taking care of the medicine first.
