Romaji:
itsumo nakayoshi de ii yo ne tte iwarete
demo dokoka [bad word]  ni natteta are wa koi datta

nandomo kuchi no naka tsubuyaite mita
kasuka na IME-JI dake o oimotometeta

toki wa koboreteiku yo chachi na yume no sekai mo
sugu ni hirogatteiku yo kimi wa iroasenu mama
 [bad word] de tobeta no sa kinosei da to satorazuni irareta nara
 [bad word] baki no ashiyubi ni mitoreta
chiisa na hana sakaseta are wa koi datta

toki wa koboreteiku yo chachi na yume no sekai mo
sugu ni hirogatteiku yo kimi wa iroasenu mama

ameagari no kirema kara sashikomu hi no hikaritachi machi o arau

itsumo nakayoshi de ii yo ne tte iwarete
demo dokoka [bad word]  ni natteta are wa koi datta

Translation:

Good Friends

You said that you're fine with us always being good friends
But somewhere inside me became blue
That must be love

I've tried muttering it in my mouth over and over again
I was pursuing only a faint image

Time is always spilling
Even into the world of a cheesy dream
It spreads out quickly
You are the only one that remains colourful

Flying away with a practical joke
Without realizing that it's merely my imagination

I admire the way your toes look in your sandals
With small flowers blooming around you
That must be love

Time is always spilling
Even into the world of a cheesy dream
It spreads out quickly
You are the only one that remains colourful

After the rain turns into wisp
The plugged light from our sun
Will bathe the city

You said that you're fine with us always being good friends
But somewhere inside me became blue
That must be love
