BluemingIU

This is a track from IU’s fifth mini-album in Korea, Love Poem, released in 2019.
Set to a bouncy guitar sound, IU’s rhythmical vocals make it an extremely cute song.
The opening lyric, “Mohae?” is a word that Koreans in love use as naturally and frequently as breathing—about as often as they say “annyeong.” It means “What are you doing?”, but it carries the nuance that the person asking is someone you like or are curious about.
You ask “mohae?” because you care—because you like them.
It’s an adorable love song that captures the real, everyday feelings of young people.
You & IIU

It’s a song that truly makes you think, “As expected of the nation’s little sister!” It’s about liking an older man who won’t notice you, wishing you could fast-forward time, grow up, and meet him.
She’s probably super cute but still treated like a kid sister.
In the MV, she builds a time machine to go see him—a quintessentially IU concept, executed brilliantly!
Palette (Feat.G-DRAGON)IU

This is the title track from IU’s fourth album, Palette, released when she turned 25.
With her colorful charm, IU seems to look at herself at that moment and think, “This is who I am,” and “These are the things I like.” IU’s whispery, cute vocals, along with BIGBANG’s G-DRAGON delivering a rap like an older oppa speaking to her, add a great touch.
Twenty-five—somewhere between grown-up and still young.
Many people will likely relate to IU’s honest, down-to-earth feelings.
PeachIU

IU and Sulli, the former f(x) member who sadly passed away in 2019, met through TV appearances and were known for being close even in private.
Fans called Sulli “Peach,” which is likely why the song is titled “Peach.” From a male perspective, the lyrics shower Sulli with compliments—‘She’s so cute!’—overflowing with affection.
You can really feel how close they were.
BBIBBIIU

The title “BBIBBI” also appears in the lyrics, and it has a cute ring to it, doesn’t it? In fact, it refers to warning sounds like “beep-beep!” or “bzzz!” Since things like your favorite clothes, hobbies, friendships, and romantic relationships are all private matters, there’s a line between what others can and can’t say about them.
This song seems to carry the message: “I’ll do things the way I like,” and if someone crosses the line, “Beep! That’s a no.” While it has a laid-back, chill sound, there’s also a theory that it reflects IU’s true feelings about being troubled by the media and malicious fans.
Our Happy EndingIU

It’s the ending song from the IU-led drama Hotel Del Luna—a very lovely ballad, though unfortunately it hasn’t been officially released.
The song carries the wishful thoughts of “What will become of the two lovers’ ending?” and “I hope it won’t be a sad one.” IU’s voice slips straight into your heart, as if a close friend were singing right beside you.
This song has that same charm.
DramaIU

It’s one of IU’s signature concert songs.
The recorder’s timbre and other elements are striking, giving it a fairytale-like soundtrack vibe—such a cute track.
It feels like she overlays the happy moments with her lover onto a drama.
When the romance ends, she’s left alone on the set, and before she knows it, the love story has already been wrapped up.
That’s so heartbreaking, isn’t it?
