I never understood what was the missing link

so tell me everything must always equal two or nothing else is true

and I'll believe you 'cause your X is equal to my Y but equations pass me by

so will you take just a little of my mind and subtract it from my soul
add a fraction of your half and you'll see it makes me whole
multiply it by the times that we've never been apart
you'll see nothing can divide just a heart plus a heart

and by the time I calculated the correct solution
the question had escaped me and so did the conclusion

o romance eu vomito, só ando musical mesmo.
