Kimi no koto zenbu
Wakatte agetai keredo
Tsuraku te mo gomakasu
Itsumo egao de

BUT I KNOW namida wo
Koraeteiru ne zutto
Sono mune ga
Koware sou na kurai

Tsuyogatte ite mo kimi no hitomi wo mire ba
Wakaru yo sugu ni ne YOU'RE MY BOYFRIEND
SO YOU CAN LEAN ON ME

Sono omoi ha todoi teru yo
Mune no oku ni hibii teru yo
Kotoba ni dasa naku tatte
I KNOW YOUR HEART soba ni iru yo

Ima wa tooku hanarete ite mo
Mune no koe wa kikoe teru yo
Kotoba ni dasa nakute mo wakaru yo
Zutto YOU'RE MY BOYFRIEND

GIRL, I KNOW kimi no koto
GIRL, I know omou koto
Jibun wo seme teru kimi no kokoro

AND I KNOW namida wo
