Grammar Points
-는/은 (Topic Particle)
The topic particle -는/은 marks the topic of a sentence—what you’re talking about. Use -는 after vowels and -은 after consonants. In this song, Moonsoo repeatedly uses “아빠는” to establish “dad” as the main topic of his complaints and affection.
| 한국어 | Romanization | English |
|---|---|---|
| 아빠는 나를 잘 몰라. | a-ppa-neun na-reul jal mol-la | Dad doesn’t know me well. |
| 나는 학생이에요. | na-neun hak-saeng-i-e-yo | I am a student. |
| 이 책은 재미있어요. | i chae-geun jae-mi-it-seo-yo | This book is interesting. |
-ㄹ/을 수 있다 (Ability/Possibility)
This pattern expresses ability or possibility, similar to “can” in English. Attach -ㄹ 수 있다 to verb stems ending in vowels and -을 수 있다 to those ending in consonants. Moonsoo proudly uses this to boast about his secret abilities!
| 한국어 | Romanization | English |
|---|---|---|
| 난 한글도 읽을 수 있는데. | nan han-geul-do il-geul su it-neun-de | I can even read Hangul. |

Culture Note
Lucid Fall (루시드폴), whose real name is Jo Yun-seok, is a unique figure in Korean music. Before becoming a singer-songwriter, he earned a PhD in biology and worked as a researcher. He later moved to Jeju Island to run a tangerine farm while continuing his music career. His songs often reflect themes of nature, simple living, and quiet observation of everyday life.
“Moonsoo’s Secret” showcases the special bond Koreans have with their pets. In Korea, it’s common for pet owners to call themselves “엄마” (mom) or “아빠” (dad) to their pets, treating them as family members. The name Moonsoo (문수) is a traditional Korean name often given to boys, which makes it extra endearing that it belongs to a puppy in this song!
Fun fact! Lucid Fall is known for his gentle, storytelling style of songwriting. He often writes from unexpected perspectives—in this case, a mischievous dog who secretly watches TV, reads Hangul, and even creates email accounts when his owner is away! The song also references “대한이형” (big brother Daehan), the neighbor’s dog who Moonsoo admires and hopes to grow up to be like.
