Todoketai todokanai kono omoi o
Karamawari shita mama no boku no jounetsu
Yomikirenai zasshi no peeji
Yomanakucha ikenai ki ni naru yo
Fuete iku terebi no channeru
Zenbu minakya okurechau no kana
Okashi na yume miru n da ie no mae no kouen de
Kimi ni nageta booru ga tochuu de ochichau n da yo
Heya no sumi tsumareta geemu sofuto
Yaranakucha imi ga nai no kana
Teeburu no mukou no kimi ni shaberi kakete iru no ni
Kimi wa hyoujou hitotsu kaete wa kurenai
Konna ni chikaku ni boku ga iru no ni

Nani mo kamo ga yugande iku
Nani mo shiranai kokoro ni modoretara ii no ni na
I want to send you my feelings, but they can’t reach you
My passion for you remains futile
I didn’t finish reading a page of the magazine
It gets to me that I have to read it
The number of channels on the TV increases
Will I fall behind if I don’t watch them all?
I’m having a weird dream, where, at the park in front of my house
The ball that I threw at you falls down midway
Games are gathered in a corner of my room
Do they have no point if I don’t play them?
Even though I’m talking to you across the table
You won’t change a single expression for me
Even though I’m so close to you
My feelings can’t reach you, can’t reach you, so I wonder what’s truly precious to me
Somehow, it feels like I’m being controlled by someone else
My heart really belongs to me
I can’t hear your voice, nor can it reach me; it gets blocked by the traffic and vanishes
Just about everything might become distorted
If only I could go back to having an ignorant heart
