Текст песни FTISLAND - Theory of Happiness

Sakihokore na mo naki hana yo nanigenai hibi no naka de hikari o abi te

nobashi ta kono te ga te ni shi ta mono nado wazuka
itsunomanika mata egao o hitorijime shi te i ta
semai kokoro no naka ni shimaeru yō na chīsana yorokobi nanka zenbu
shiawase ja nai to nisemono to imasara kizui ta boku no oroka

moshi ji ga modoseru no nara kimi ga i ta ano koro e modori tai
shiawase wa ubau no de naku tebanashi te ataeru sono yūki no betsumei

hirai ta kono me ga me ni shi ta keshiki wa wazuka
daiji na mono hodo tōmei da to kizuka nai mama
arigatō, mo gomen, mo iwa naku natte
itsuka kūki no yō ni natte shitta
demo kimi ga i nai to iki ga deki nai

sakihokoru na mo naki hana ga kimi to i ta hibi no yō ni mabushiku te
shiawase wa sagasu no de naku tada boku o yasashiku tsutsumu kūki no betsumei

sukitōru kawa no nagare de maruku natta ishi no yō ni

sakihokore na mo naki hana yo onaji ayamachi mō okasa nu yō ni
sasayaka na hana no kaori yo awai iro o yakitsuke ta mune ni
moshi ji ga modoseru no nara kimi ga i ta ano koro e modori tai
shiawase wa ubau no de naku tebanashi te ataeru sono yūki no betsumei
