Kimi no koto zenbu wakatteagetai kedo
Tsurakutemo gomakasu itsumo egao de
BUT I KNOW namida wo koraeteru ne zutto
Sono mune ga kowaresouna kurai

Tsuyogatteitemo kimi no hitomi wo mireba
Wakaru yo sugu ni ne YOU'RE MY BOYFRIEND
SO YOU CAN LEAN ON ME

Sono omoi wa todoiteru yo
Mune no oku ni hibiiteru yo
Kotoba ni dasanakutatte
I KNOW YOUR HEART soba ni iru yo
Ima wa tooku hanareteitemo
Mune no koe wa kikoeteru yo
Kotoba ni dasanakutemo wakaru yo
Zutto YOU'RE MY BOYFRIEND

GIRL KNOW kimi no koto
GIRL KNOW omou koto
Jibun wo semeteru kimi no kokoro
AND I KNOW namida wo
Misenai youni zutto
Fuan de mune ga ippai no toki mo

Tsuyogatteitemo kimi no hitomi wo mireba
Wakaru yo sugu ni ne YOU'RE MY BEST FRIEND
SO YOU CAN LEAN ON ME

Sono omoi wa todoiteru yo
Mune no oku ni hibiiteru yo
Kotoba ni dasanakutatte
I KNOW YOUR HEART soba ni iru yo
Ima wa tooku hanareteitemo
Mune no koe wa kikoeteru yo
Kotoba ni dasanakutemo wakaru yo
Zutto YOU'RE MY BEST FRIEND

Futari no kokoro tsunagu terepashii
Futari wo hikisaku mono nante nai
Omoitsuzuketeru yo doko ni itemo
Kokoro wa tsunagatteiru kara

YES I KNOW kimi no koto
AND YOU KNOW watashi no koto mo
Shinjiatteiru kara daijoubu
SO YOU CAN LEAN ON ME

Sono omoi wa todoiteru yo
Mune no oku ni hibiiteru yo
Kotoba ni dasanakutatte
I KNOW YOUR HEART soba ni iru yo
Ima wa tooku hanareteitemo
Mune no koe wa kikoeteru yo
Kotoba ni dasanakutemo wakaru yo
Zutto YOU'RE MY BEST FRIEND
