Koigokoro wa tsutaekirenai ze
Watashi no koto mo wakatte hoshii ze
Ironna koto tomerarenai kurai
Kurushimi datte itoshisa ni natta

Ureshikereba egao ni nareru ze
Setsunasugiru to naite shimau kedo
Kitto zenbu koi no kimochi nara
Tsuyoku naru yo sou shinjitai ze

Doushite mune ga itamu kurai
Omae no egao kotaete hibiku
Me wo sorashi warau terekakushi
Suki to iu kotoba ga ienai

Kirameku watashi no kimochi anata no tame ni aru no yo
Nakushita kotoba de suki to tonaeta
Makenaide omoi kokoro
Sukitootta hitomi yake ni atsukute tomerarenakute
Watashi no omoi wo nosete hanatsu ze Love's spark!!

Koigokoro ga todokanai nante
Sonna koto wa zankoku sugiru ze
Kanashimi nara hoshiku wa nai kara
Koi nante shitaku wa nai n da yo

Nakitsukarete bed moguru kara
Omae no kao mo omoidasenai ze
Kotoba dake de unuborechau kara
Sore dake de tachiagarenai ze

Omae wa watashi wo suki janai
Sarigenaku daitarishinaide yo
Konna yasashisa wa iranai ze
Suki janai nara furenaide

Watashi no omoi wa mayoi yorimichi shinai de mezasu
Zenbu zenbu anata no mae ni iku
Kidzuite shinjite kokoro
Kujikesou ni naru dakedo mada mada akiramenai ze
Watashi no kimochi wo nosete hanatsu ze Love's spark!!

Kirameku watashi no kimochi anata no tame ni aru no yo
Nakushita kotoba de suki to tonaeta
Makenaide omoi kokoro
Sukitootta hitomi yake ni atsukute tomerarenakute
Watashi no omoi hanatsu ze Koiiro Master Spark
