This is one of Bleach opening songs for episode 121 - 143

Oreta awai tsubasa
Kimi wa sukoshi aosugiru
sora ni tsukareta dake sa
mou dareka no tame janakute
jibun no tame ni waratte ii yo

izen to toshi no bion ga toutsuu
uchigawa ni tomaru go osoku
toki wa ubau ni koukanosha
im ga arya to wa urahara ni

tarinai kotoba no hitomi
no ma ni de umetanain darou
Mou wakaranai yo

semete umero, wakatta?
jiyuu ni oyogetara
naa sora mo irana ne ni
kinou made no koto wo
iitsubasanakutemo
asu ni makaeru no ni

Oreta awai tsubasa
Kimi wa sukoshi aosugiru
sora ni tsukareta dake sa
mou dareka no tame janakute
jibun no tame ni waratte ii yo

--------------------------------------

Your fragile, folded wings are just tired from the pure blue sky.
You don't have to force your smiles for anyone
It's okay to smile... for yourself.
That lonely feeling keeps creeping up on me
A single candle still burns inside
There shouldn't be an expensive chandelier in a wild place like this
Can I really bury it all with empty words?
I don't even know anymore...
As long as we can swim freely in our dreams
we won't need that sky anymore.
Even if you can't let go of the past
I'll still be there to meet you tomorrow
Your fragile, folded wings are just tired from the pure blue sky.
You don't have to force your smiles for anyone.
It's okay to smile... for yourself.

Side note: The song gave a feeling of sadness... quiet sadness.. somehow.
