『Undefined Love／未定義の恋』
Instrumental Prompt: Instrumental math-rock with clean shimmering guitars in interlocking polyrhythms, sharp tapping lines, and bright staccato arpeggios. Dry punchy drums in complex odd-time grooves, stop-and-go breaks, tight snare, and dynamic fills. Warm melodic bass weaving counterlines, airy synth pads adding subtle philosophical atmosphere. Precise, analytical tension gradually opening into a cathartic harmonic lift with a crisp, wide, high-clarity mix. Male Vocal Prompt: Calm, restrained male vocal with minimal vibrato, clipped consonants, analytical phrasing, clean indie tone. Slightly detached, steady, focused on clarity over power. Female Vocal Prompt: Warm, expressive female vocal with airy highs, emotional vibrato, smooth legato phrasing, sudden accents, and a bright, intuitive, philosophical feel.

Lyrics
『Undefined Love／未定義の恋』
感情ゼロの青年×哲学少女。
“未定義の恋”が二人の方程式を壊していく。
数学×恋愛×デュエットの切ないポリリズム。
A young man with zero emotions and a philosophical girl.
An "undefined love" destroys the equation between these two.
A heartbreaking polyrhythm of mathematics, love, and a duet.
Intro
Factor / error / unstable
ゼロで固定された感情値
「好き」は未定義のまま
僕の内部でノイズが揺れる
Verse 1
閉じた心＝関数
代入しても変わらない
Love → 無反応
グラフは水平のまま
感情は乱数
理性は定数
僕はただ
揺れ幅を消したかった
Break
触れられると乱れる
計算が狂う
君だけが誤差を生む
Verse 2
好きは証明じゃない
心が鳴る現象
論理より先に触れる
意味よりも先に揺れる
未定義の痛み
名前のない温度
「今」を抱いて進むの
Build-up
係数が大きすぎる
論理じゃ測れないよ
式が乱れるのが怖い
乱れこそ生きてる証拠だよ
New Riff
ゼロに固定した変数の蓋を
開けた瞬間
君の声だけが
真っ直ぐ刺さった
正解のない世界で
ひとつだけ確かだった
触れられた時の「乱れ」
それがあなたを動かしたの
Slow Section
心は直線じゃない
始点も終点も消える
だから私は “好き” を投げた
定義できないからこそ価値がある
あなたの静止を壊したかった
Final Riff
未定義
だから触れる
証明不可
だから寄り添う
感情
方程式
不確定要素 = 名前のない恋
Outro
zero
error
value unknown
恋は解けないまま続く
未定義のまま
それでも
僕は君に近づいていく
English Version
Intro
factor / error / unstable
emotion value fixed at zero
“love” remains undefined
noise trembles inside my system
---
Verse 1
closed heart = function
substitute… no change
love → no response
the graph stays flat
feelings = random numbers
reason = constant
I just
wanted to erase the amplitude
---
Break
your touch distorts me
calculations collapse
only you create error
---
Verse 2
liking isn’t proof
it’s a phenomenon of the heart
it reaches me before logic
it shakes me before meaning
undefined ache
a nameless warmth
I embrace the “now” and move on
---
Build-up
the coefficient is too big
logic can’t measure it
the distortion scares me
distortion means you’re alive
---
New Riff
the lid on the variable I fixed at zero
the moment I opened it
only your voice
pierced straight through
in a world without answers
one thing was certain
the “distortion” when I touched you
that is what moved you
---
Slow Section
the heart isn’t a straight line
beginnings and endings fade
that’s why I threw “love” at you
its worth lies in its lack of definition
I wanted to break your stillness
---
Final Riff
undefined
so I reach
unprovable
so I stay
emotion ×
equation ×
uncertainty = a nameless love
---
Outro
zero
error
value unknown
love continues unsolved
still undefined
and still—
I move closer to you
