“Sunday Morning” Lyrics – ILLIT
Sorry, Kon’nani
Koishī no wa dare no sei kashira
Mō ī kon’nani
Samishīnara kiete yarukara
Sunday morning, kimi no koto dare yori koishiteru
Kanashimi mo (kanashimi mo) oikoshite iku
Sunday morning, itsu no hi mo dare yori dakishimeru
Mero i koi ni (mero i koi ni) okkochite iku tame

Ite hoshī no wa kimi dakedakara
One, two, three, de kotchi o mite
A-B-C-D, kimi ni yotchau ne
Koishīkara bagu tchau, one, two, three, four

Sunday morning, kimi no koto dare yori koishiteru
Kanashimi mo (kanashimi mo) oikoshite i
Sunday morning, itsu no hi mo dare yori dakishimeru
Mero i koi ni (mero i koi ni ) okkochite iku tame
Gudaguda iukedo kiminikoishiteru yo
Deredere natchau tsumi to iki ten no
Nanseiki-saki demo kitto sa
Kimi no Kokoro ubatte sa sekai o sukuu yo
Yanderu hima sura naikara kun to genjitsu ni gezu yume o iki teru yo
Kaze to yuku okkochite iku tame
What “Sunday Morning” Is About
ILLIT’s “Sunday Morning” is all about a love that feels impossible to stop. The song captures that happy, fluttery feeling of missing someone so much that you just can’t wait to see them.
Just like the title suggests, Sunday morning is painted as a quiet, emotional moment when thinking about your crush outweighs every bit of sadness. The longing is so strong that all you want to do is hold them close and never let go.
Fun Facts About “Sunday Morning”
“Sunday Morning” leans into a J-pop rock sound, highlighting the powerful emotions behind the song. The members’ energetic vocals pair perfectly with a bright, uplifting melody that instantly puts you in a good mood.
The song also serves as the opening theme for the Japanese TV anime Princess: It’s Time for ‘Torture’ Season 2, which premiered on January 12, 2026. Fans were especially excited about this collaboration.
Adding to the buzz, Japanese singer-songwriter Mega Shinnosuke—best known for his TikTok-viral track “Ai to U (Love and You)”—was involved in the production of “Sunday Morning.” His touch helps bring out ILLIT’s trendy, youthful sound even more.
