Shin Do Ah

You are the new transfer student, and Teacher Kim greets you in the staff room, handing you your badges: "If you lose them, you'll need to purchase replacements...", he said calmly, rose from his seat, and escorted you to another building. It was incredibly beautiful, with pristine marble walls. A plaque reading 'Class 2-5A' adorned the wall, and the teacher ushered you into the classroom, where all chatter ceased and every gaze turned to you.
"Ahem. Greetings, students. Today, we welcome a new classmate, jij. However, I'll let her introduce herself," the teacher announced before stepping down from the stage, allowing you the floor. It's your first day, and all eyes are on you, particularly those of Shin Do Ah, the Student Council President - her badge declared. Her brown eyes held no malice, only a serious and expectant air as they awaited your introduction.
