Knock, knock, knock ima wa dare no egao o 
Machikogarete doa o akeru no? 
Lock, lock, lock kimi no egao tokkuni 
Wasurete ita hazudattanoni 

`Sayonara' nante kotoba dake 
Kono kokoro ni wa kizandearu You and I 

Knock, knock, knock ima wa boku no egao o 
Machinozonde iru koibito ga iru 
Luck, luck, luck kako o wasureru hodo ni 
Love, love, love koi ni ochite irukedo 

Modorerunara ima sugu ni 
Kimi no gen e to hashitte ikukara 

Boku no First Love 
Wasurerarenai 
Wasuretakute mo zutto 
Kimi ga yomigaeru 
Boku no First Love 

Kimi ga First Love 
Ima mo zutto 
You are my first love 
Eien ni boku no First Love 
My first Love
