It’s the title track of the 2020 mini-album WE:TH.

At first listen the song can feel intense, but the members’ vocal delivery and the way the chorus bursts with emotion give it a deeply aching quality.

While wishing happiness for a loved one, the lyrics confess a hidden hope that they might be unhappy instead… torn between wanting them to go so far away that the time they spent in love can no longer be remembered, and wanting that person to long for love again.

The white daisies on the cover symbolize “innocence.” The song also plays on the Korean word deida, which means being burned or going through something painful and difficult, to portray the wounds of love—another layer of poignancy.

In her solo activities in November 2025, Miyeon delivered a pop ballad steeped in the lingering afterglow of a farewell.

While she’s known for dynamic tracks with (G)I-DLE, this title song from her second solo mini-album, “MY, Lover,” layers a clear, pure vocal over the spacious interplay of delicate piano melodies and a rhythmic beat, richly portraying the call of a loved one that doesn’t fade even after parting.

The lingering memory of a name that echoes like reverb, and a sense of time that drifts between dreams and reality, are carefully woven together, conveying a moving stance of acceptance rather than actively trying to forget.

The beauty of her vocal delivery stands out against the understated accompaniment, precisely because it is stripped of excessive ornamentation.

It’s a song you’ll want to play on a long autumn night.
