KAI “Adult Swim” Lyrics

Hangul

adult swim

Hey (hey), 지금부터는 조금 위험해
한 발씩, come in slowly
Babe (babe), 너의 허리에 팔을 감을게 (uh)
You can lean on me

겁먹을 필요 없어, 두 눈을 살짝 감고
나에게 너를 맡겨, 제일 깊은 곳으로 함께

Dive in (mmm)
Adult swim (mmm)
Dive in (mmm)
Adult swim (mmm)

Turn it up (mmm)
Adult swim (mmm)
Dive in (mmm)
Adult swim (mmm)

Sway (sway), 파도에 앞뒤로, 옆으로, 흔들려도 돼
스릴 있게, yeah, yeah, yeah
Same (same), 내 맘도 다를 건 없는 걸, 한순간 awake
빠져드네, yeah, yeah

목적진 따로 없어, 속도를 좀 더 올려
날 계속 끌어당겨, 제일 깊은 곳으로 함께

Shake it, shake it, shake it, shake it, shake it for me
Shake it, shake it, shake it, shake it, shake it for me (hey, hey)

Make it fast, make it slow
Shake it, shake it, shake it, shake it, shake it for me

Adult swim

Hey (Hey), from now on, it’s a little dangerous
Step by step, come in slowly

Let’s increase the speed a bit more
Keep pulling me in
Together, into the deepest place

KAI “Adult Swim” Meaning

Kai’s “Adult Swim” is a sensual and atmospheric song that uses water as a metaphor for love, intimacy, and emotional vulnerability. Through its smooth melodies and immersive lyrics, the track explores the experience of letting go of fear and fully embracing a deep connection with another person.

The song’s central metaphor compares romance to swimming. The early stages of a relationship are portrayed as a calm and effortless float, while the chorus symbolizes venturing into deeper waters. This transition represents moving beyond surface-level attraction and entering a more profound emotional and physical bond.

Trust is another key theme throughout the song. The lyrics encourage a partner to let down their defenses, rely on one another, and face uncertainty together. Rather than viewing vulnerability as something frightening, “Adult Swim” presents it as an essential part of building a meaningful connection.

The track also reflects personal growth and maturity. As one of Kai’s releases following his military hiatus, “Adult Swim” symbolizes a new chapter in his artistic journey. The song embraces a more confident and fearless outlook, highlighting themes of freedom, self-assurance, and emotional openness.

Ultimately, “Adult Swim” is a sophisticated exploration of intimacy and trust. By using the imagery of diving into deep water, Kai captures the excitement, vulnerability, and beauty of fully surrendering to love and connection.
