Romaji:
Bokura ha hanarebanare tama ni attemo wadai ga nai
Issho ni itai keredo tonikaku jikan ga tarinai
Hito ga inai toko ni yukou yasumi ga toretara
Itsu no ma ni ka bokura mo wakai tsumori ga toshi wo totta
Kurai hanashi ni bakari yatara kuwashiku natta mon da
Sorezore futari isogashiku ase kaite
Subarashii hibi da chikara afure subete wo sutete boku ha ikiteru
Kimi ha boku wo wasureru kara sono koro ni ha sugu ni kimi ni ai ni yukeru
Natsukashii uta mo waraigao mo subete wo sutete boku ha ikiteru
Soredemo kimi wo omoidaseba sonna toki ha nanimo sezu ni nemuru nemuru
Asa mo yoru mo utainagara tokidoki ha bon'yari kangaeru
Kimi ha boku wo wasureru kara sou sureba mou sugu ni kimi ni ai ni yukeru

English:
We're separated, and though we meet up sometimes, there's nothing to talk about
I want to be with you, but there just isn't enough time
Let's go somewhere where there's no one around, when we get a break
All of a sudden, though we meant to stay young, we've grown older too
We've recklessly ended up knowledgeable on nothing but gloomy stories
We're so busy with our own things we sweat up a storm
What wonderful days! Power overflows, and I live having thrown everything away
You will forget me, so when that happens, I'll be able to come see you right away
The nostalgic song and smiling face both--I live having thrown everything away
If even so I remember you, at that time, I'll do nothing and go to sleep, go to sleep
While singing both morning and night, sometimes I absentmindedly consider how
You will forget me, so should that happen, I'll be able to come see you right away
