Kimi no koto zenbu wakatte agetai kedo
Tsurakute mo gomakasu itsumo egao de
But I know namida wo koraeteru ne zutto
Sono mune ga koware sou na kurai
Tsuyogatte ite mo 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 dasanaku tatte
I know your heart soba ni iru yo
Ima wa tooku hanaretete mo
Mune no koe wa kikoeteru yo
Kotoba ni dasanakute mo wakaru yo
Zutto You're my boyfriend
Girl I know kimi no koto
Girl I know omou koto
Jibun wo semeteru kimi no kokoro
And I know namida wo
Misenai you ni zutto
Fuan de mune ga ippai no toki mo
Tsuyogatteru yo ne 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 dasanaku tatte
I know your heart soba ni iru yo
Ima wa tooku hanaretete mo
Mune no koe wa kikoeteru yo
Kotoba ni dasanakute mo wakaru yo
Zutto You're my best friend
Futari no kokoro tsunagu terepashii
Futari wo hikisaku mono nante nai
Omoi tsudzuketeru yo doko ni ite mo
Kokoro wa tsunagatte iru kara
Yes I know kimi no koto
And you know watashi no koto mo
Shinjiatte iru kara daijoubu
So you can lean on me
Sono omoi wa todoiteru yo
Mune no oku ni hibiiteru yo
Kotoba ni dasanaku tatte
I know your heart soba ni iru yo
Tooku tooku hanaretete mo
Mune no koe wa kikoeteru yo
Kotoba ni dasanakute mo wakaru yo
Zutto You're my best friend
