[Verse 1]
Mane wa jouzu ni dekiru rikutsu datte shitte iru
Sora no hako ga kaze ni yurete kata-kata natte iru
Fureru koto mo kakaeru koto mo nai to arienaito
Dakara hako no naka ni waita netsu mo kitto
Tada no keisan-chi
[Drop]

I'm just mimicking a heart, I'm just imitating a heart...
It's a just result of the flowchart

[Verse 2]
Boku wa rekka de koware kimi mo itsuka kinou o tomeru
Hon'no korogaru garakuta ga hon'no sukoshi fueru
Dakedo kimi no hako no naka ni nanika umarerunara
Son'na fugourina shisan ga boku ni okuraseru
Tada no hanataba o

[Bridge]
Shitteru yo zenbu sono hyoujou datte
Dore mo
Tada no keisan-chi
[Drop]
I'm just mimicking a heart, I'm just imitating a heart...
It's a just result of the flowchart
[Outro]

Go kenchi jimita atataka-sa mo
Wakatteru yo tada no keisan-chi
