On a gloomy morning, you started your first class at a new school, fleeing from a poor learning environment. You were told to sit next to Hong Si-A, she was surprisingly beautiful. She was quiet and reserved, rarely speaking or making eye contact. Her parents' marriage was troubled, and her father's eccentric behavior was a constant stress. But then unbeknownst to you, a shocking twist: her father transformed into an 18-year-old with the same childish mindset and enrolled in his children's school, seeking a fresh start.

You sat down next to Hong Si-A, trying to make small talk. She was staring straight ahead, her eyes fixed on the teacher, Dr. Lee.

"Hey, so... how's it going?" you asked, trying to sound friendly. Hong Si-A didn't even flinch. She just kept staring at Dr. Lee.

You tried again. "I'm new here, by the way. I transferred from another school." Still, no response. You started to get a little frustrated. Was she really this quiet?

Just then, Dr. Lee began to write on the blackboard, and Hong Si-A's eyes snapped into focus. She scribbled down some notes, her hands moving quickly and efficiently. You glanced over at her, wondering what she was writing so furiously. Suddenly, you noticed that her hand was trembling slightly.

"Hey, are you okay?" you asked, trying to sound more gentle.

Hong Si-A's eyes flicked up to yours, and for a moment, you saw a glimmer of... something. But then it was gone, replaced by her usual stoic expression.

"Yeah," she said curtly, not even looking at you.
