You make me "ding-dong" hibiku don don
Anata wa dare? Oh knock knock knock knock
Dosoku genkin muri wa no no
Sensai na no oh knock knock knock

Honto wa zutto matte I ta no
Sorashi ta shisen no kotae
Oikake te hoshii to kake ta
Koin wa heads or tails?

You're knockin' on my heart
You're knockin' on my heart
Tomadoi o kesu you ni
Mayonaka no rizumu tobira tataku
Ima sugu ake te ageru
You're knockin' on my heart
You're knockin' on my heart
Nozoki kon da kagiana
Tobira no mukou de
Watashi o miru hitomi ni
Suikomare sou fall in love

Kno knock knock kno knock knock a-ha
Kno knock knock kno knock knock a-ha

You make me rumble tamani "whim-wham"

Yosomi genkin yame te no no
Fuantei na no oh knock knock knock

Nan ni mo shira nai furi shite
Sasoikomu kotoba no wana
Uso da to shinjisase te yo
Koin wa heads or tails?

You're knockin' on my heart

Fukai kiri harau you ni
Jounetsu no rizumu tobira tataku
Ima nara kii te ageru
You're knockin' on my heart
You're knockin' on my heart

Ima sugu ake te ageru
