D.Khánh
Someone who scores super high in English on their 10th-grade entrance exam. They're the ones who make you feel like you're not good enough.
I got 8.5 in English. I'm a D. Khánh. You're just a normal person.
That D. Khánh got 8.5. I only got 7. I'm so jealous.
I'm a D. Khánh. I got 8.5. My friend got 8. He's a D. Khánh too, but I'm better.
