It’s an upbeat tune that showcases Hatsune Miku’s cute vocals to the fullest.
The lyrics are sprinkled with RPG terminology, portraying love as a game.

I really, really, really, really, really hate it.Amala

The track is by Amala and was released in March 2025.
Its rhythmic melodic lines and playful back-and-forth vocal work make you want to listen to it over and over again.
And while they keep saying they “hate” each other, the lyrics’ storytelling—about a relationship they can’t seem to cut off—is so compelling that you can’t help but wonder, “What will happen to these two next?” The high-quality animated music video is a must-see!

This song is an irresistibly cool Vocaloid tune, flowing from rapid-fire vocal parts into a polyrhythmic interlude.

collapse; fainting spell (colloquial/slang)iyowa
The bouncing piano and rhythms, along with the wavering, unstable synths, somehow feel surprisingly comfortable.

Beyond the song itself, the stylish animated MV—featuring illustrations drawn by Iyowa—also became a hot topic.
