Lyrics are something like this (if i am wrong say so):
Don ‘ t look back .
Keep moving forward
Gotta be tough on my own x2

Far away from there
No one else is here
My heart is nowhere

mune o mitasu garan dō ni
mō anata mo daremo inai
hitorikiri kake ta tsuki aogu yo ni
You were gone??

Don ‘ t look back .
Keep moving forward
Gotta be tough on my own
nani mo osore zu iru tsuyo sa ga
sugu ni hoshiku te kokoro ni atsuku tetsu o matotta
Don ‘ t look back .
Keep moving forward
Gotta be tough on my own
kataku toji ta tobira no kagi wa
ano hi, anata to saigo ni waratta hi ni kakushi ta

I called out to you
Called to everyone
But no one answered

satta hito no yukue nado
oikake te mo munashii dake

Don ‘ t let me out .
I must stay now
Even though I don ‘ t want to
nani mo yurusazu kirisutete wa
dare no kotoba mo shinjiru yori mo saki ni utagatta
Don ‘ t let me out . I must stay now
Even though I don ‘ t want to
mizukara no te de tsukuru kabe ga
kizui ta toki ni tōku setake sae mo koe te i ta ah??

kakuzetsu. sekibaku. kōryō. kūhaku. zetsubō sono shinshō fūkei
Everytime I feel alone ,
You are fading away mō nani mo todoki wa shi nai

Don ‘ t look back .
Keep moving forward
Gotta be tough on my own
nani mo osore zu iru tsuyo sa ga
sugu ni hoshiku te kokoro ni atsuku tetsu o matotta
Don ‘ t look back .
Keep moving forward
Gotta be tough on my own
kataku toji ta tobira o ake te
ano hi no yō ni waraeru hi ga itsuka ki ta nara??

Don ‘ t look back .
Keep moving forward
Gotta be tough on my own??
