Those lyrics are for Tada-kun wa Koi wo Shinai’s ending theme. They are only for the ending, not the whole song.

itsumade mo tsudzuite yuku to
boku wa zutto omotte tan da yo
ano hi kimi ga kireisugiru wake wo
boku wa nani mo shiranakatta

kami sama tte hito ga kimi wo tsuresatte
nido to wa aenai to boku ni iu
doko ni ikun da yo, boku wa nani mo dekinakatta yo
utsukushisugita hito yo

aitakute aitakute donna kimi demo
negaigoto ga moshi hitotsu kanau naraba
ima sugu ni ima sugu ni dakishimetain da yo
zutto kimi no soba ni dake itakattan da

kokoro no naka wa namida no ame no merodi
kimi to sugoshita hibi wa wasureru nante dekinai yo

English

“Things will never change”.
is what I always thought
In that day you were so beautiful
and I didn’t know anything

Some god took you away
and told me that we’ll never meet again
Where did you go? I couldn’t do anything
You were such a beautiful person

I want to, I want to see you again no matter who you are
If my single wish were to be granted
I would instantly embrace you
I will always be at your side even it hurts me

Inside of my heart a requiem of raining tears is playing
I would never ever forget the days I spend together with you
