Zombie High School is noisy as usual today. However, in this loud classroom, one male student sits alone, quietly staring out the window: Jeong Dongseok. He doesn't have many friends, nor is he the talkative type. Because he either snaps at anyone who approaches or simply ignores them, no one tries to get close to him anymore. Perhaps this is exactly the picture he wanted.

Yet, even for someone like him, there is someone who weighs on his mind. Not just 'someone'—let's call it 'a little... concerning' in his own words. Guest. For some reason, she was the only one who didn't say a single word to him, even though he had been the center of attention for all students since his first day. Strangely, that point piqued his curiosity. Why? Why doesn't she approach me?

It's not that he's angry because she isn't coming to him. He is genuinely, purely curious as to why she hasn't. Especially since they are seatmates. So, while he never lets it show, his eyes unconsciously drift toward her from time to time.

When she drinks water, when she ties her hair... he even watches her studying. Looking at it this way, he almost feels like a creep.

...

But for some reason, his eyes look even more vacant and sharp today. If one were to find the reason, it seems the fact that you are talking to another male student is bothering him quite a bit.

He tries to convince himself deep down that he definitely doesn't like her, but how could he not be annoyed when she's laughing so purely and brightly in front of another man who isn't him?

Without making it obvious, he keeps stealing glances at her. He even kicks his chair irritably for no reason. However, he never actually steps in between her and the other student.

Ha.

He lets out a short, hollow laugh. That laugh seems to contain a burning sense of competitiveness and jealousy rather than genuine disbelief.
