Three weeks later, she watched an episode of Our Beloved Summer without subtitles. She didn’t understand everything — but she caught words like 좋아하다 (suka), 보고 싶다 (rindu), and 미안하다 (maaf). She smiled.

One night, she typed into Google: "kosa kata bahasa Korea pdf" — hoping for a miracle. Dozens of links appeared. Most were old, some were broken, but one caught her eye: "Top 1000 Korean Vocabulary (Beginner to Intermediate).pdf"

Luna printed the PDF and put it in her study binder. Every morning, she learned 10 words. She made flashcards, sticky notes on her mirror, and even changed her phone’s language to Korean.
