Sunday Morning Lyrics [English]

[Verse 1]
Sorry, like this
Who made me miss you this way
No, I don't want to
Be lonely like this, I'll walk away

[Chorus]
Sunday morning, I'm into you more than anyone else
It outruns all my sorrow
Sunday morning, I'll hold you tighter than anyone else
For the sweetness of falling in love

[Verse 2]
RG? By my side
You're the only one I want
One, two, three, look here
A-B-C-D, I fall in love with you
I glitch out cause I miss you, one, two, three, four
Yeah

[Instrumental Break]

[Chorus]
Sunday morning, I'm into you more than anyone else
It outruns all my sorrow
Sunday morning, I'll hold you tighter than anyone else
For the sweetness of falling in love

[Outro]
I talk too much, but I fell for you
I melt away, drowning in this sin
Even centuries later, no matter what
I'll save the world by stealing your heart
I have no time to suffer
I'm still dreaming, not giving into reality
Following the winds and falling

Sunday Morning Song Meaning (ILLIT)

ILLIT’s "Sunday Morning" arrived as a fresh Japan digital single on January 13, 2026, marking the group’s second original Japanese release under BELIFT LAB and Universal Music Japan. Crafted in collaboration with Japanese songwriter-producer Mega Shinnosuke, the track doubles as the opening theme for the second season of the anime Tis Time for “Torture,” Princess. Positioned within the J-pop rock genre, the song blends youthful energy with nostalgic melodic textures, reflecting both emotional urgency and lyrical sincerity. Its release continues ILLIT’s momentum in Japan following earlier charting singles and expanding their global footprint.

Song Meaning:

From the outset, "Sunday Morning" unfolds like an intimate confession delivered across heartbeat rhythms — a narrative centered on the exhilarating surge of attraction that eclipses ordinary life. Rather than dwelling in conventional pop declarations, the writing captures the duality of yearning and self-awareness: an emotional tension between wanting closeness and confronting solitude. This interplay sets the tone for a story about inner conflict and resilience in the face of romantic longing.

As the song builds, it transitions into a celebration of intensity and devotion. The music’s rock-tinged arrangement underscores a sense of kinetic urgency, as if the heart itself propels forward. Love becomes a force capable of outpacing even sadness, suggesting a transformative power that reshapes the protagonist’s perspective. The imagery evoked here aligns with broader J-pop rock traditions, where sweeping feelings are expressed not just through melody but through kinetic vocal urgency and instrumental momentum.

In its second half, the track embraces playful, almost whimsical moments. Counting sequences and rhythmic breaks heighten the sense of vulnerability — as though the speaker is alternately composed and undone by their own feelings. This playful cadence speaks to the unpredictability of love: at once precise and chaotic, measured yet wildly impulsive. Through this, the song avoids flat sentimentality, choosing instead to mirror the real emotional oscillations that come with deep attraction.

The closing passages shift toward a reflective yet hopeful space. Here the narrative broadens, acknowledging emotional complexity without retreating into defeat. The music suggests that devotion and longing can coexist with personal growth and movement forward, even when those feelings feel heavier than circumstance. This balance gives the song a wistful yet resilient character, offering a sense of emotional continuity rather than resolution.

Emotional Core and Themes:

At its heart, "Sunday Morning" thrives on contrasts — the tension between solitude and closeness, stability and overwhelm, hope and reality. It captures that universal human experience of desire so intense it feels both grounding and disorienting. The themes revolve around longing as an almost gravitational pull, one that reshapes the emotional landscape of the protagonist. There’s a palpable sense of duality: the sweetness of connection paired with the sting of absence. Mega Shinnosuke’s lyrical framing keeps this emotional core accessible and vivid, while the rock-leaning production amplifies the song’s emotional urgency.

Connection with Listeners:

Listeners are drawn into "Sunday Morning" not just because of its melodic appeal, but because it maps feelings many have lived but struggled to express. The song’s narrative arc — from yearning through playful surrender to introspective resolve — mirrors the nonlinear progression of real emotional experiences. This relatability, combined with ILLIT’s expressive delivery and the song’s anime connection, widens its resonance across diverse audiences. Fans, particularly younger listeners navigating their own emotional terrain, find clarity in a story that honors both intensity and vulnerability. The blend of Japanese rock elements with pop-leaning structures also opens the song to cross-genre appeal, inviting engagement beyond traditional J-pop circles.

Conclusion:

"Sunday Morning" stands as a nuanced expression of love’s powerful sway — raw in feeling yet composed in craft. It leverages rock-infused sound and lyrical candor to explore the unpredictable nature of desire, making emotional complexity feel both immediate and universal. For ILLIT, the track not only deepens their artistic identity in the Japanese market but also reinforces their ability to tell stories that resonate emotionally and culturally. In doing so, "Sunday Morning" becomes more than a single release; it’s an invitation into a shared emotional experience that feels both personal and timeless.
