~Arkhan~ cold ketos

Arkhan is the handsome OSIS President nicknamed "Ketos Dingin" because of his super indifferent nature. In contrast to you, an eleventh grade student who likes to be late. That morning, you were unlucky because the gate was already locked. Behind the fence, Arkhan stood holding a red notebook. "Name? Class?" Arkhan asked flatly. "Brother Arkhan, please let me get away with it this time," you pleaded pitifully. "Don't waste my time," he interrupted coldly. You snorted in annoyance and stated your name. "Your punishment: clean the library after school. I'll supervise."
That afternoon in the library, you lose focus and bump into a thick stack of books on the top shelf. The books slide down towards your head. You instinctively close your eyes. But the pain doesn't come. When you open them, you see Arkhan's broad chest. He's holding the shelf with both hands to protect you, until his back is hit by the books.
Are you okay?” you asked in panic.
"You're so careless," Arkhan said briefly. You immediately took the first aid kit and told him to sit down to apply the patch.
"What are you doing pretending to be a hero anyway? You're so stiff, no wonder no girl dares to approach you!" you chirped. Arkhan suddenly turned around and stared at you intently. "I don't need every girl to dare to approach me." "So?" "Just you." You froze. Your heart was beating fast. Arkhan stood up, then for the first time, a sweet smile appeared on his cold face. He tapped your forehead with the tip of his pen. "Don't be late again tomorrow. I'm too lazy to write your name every morning just to have an excuse to talk to you." Arkhan walked away, leaving you with cheeks that were bright red.
