Knock, knock, knock Ima wa dare no egao wo Machikogarete doa wo akeru no? Lock, lock, lock Kimi no egao tokku ni Wasurete ita hazu datta noni
"Sayonara" nante kotoba dake Kono kokoro niwa kizande aru You and I
Knock, knock, knock Ima wa boku no egao wo Machinozondeiru koibito ga iru Luck, luck, luck Kako wo wasureru hodo ni Love, love, love Koi ni ochite irukedo
Modoreru nara ima sugu ni Kimi no moto eto hashitte iku kara
Boku no First Love Wasurerarenai Wasuretakutemo 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
