Ft Island - Shiawase Theory / Theory of Happiness lyrics + translation

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
toki no nagare ga ibitsu na kokoro o

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

TRANSLATION

That nameless flower that blooms so full
Take a light on your day to day self

It doesn't got many things with this hand I reach out
I had realized that I kept this smile only to myself
I put away all into my narrow heart, the little joys
now I realized its too late and showed only fake happiness
not the real ones, I'm so stupid

If I could reverse time, I'll go back to those days I met you
It's a courage to be able to give happiness rather than depriving it

These eyes havent seen landscapes
While being unaware that these things are important
Not able to say, I'm sorry and Thank you
I know that I'll be like the air someday
but I can't breathe if you're not there

That nameless flower that blooms so full
is as bright as the days when I was with you
Rather than looking for happiness, I just want to be wrap like a gentle air

Like a stone that was rounded by river flows
time flies just like my heart

That nameless flower that blooms so full that I won't make the same mistakes again
That modest flower, your scent & color I want to burned it inside my heart
If I could reverse time, I'll go back to those days I met you
It's a courage to be able to give happiness rather than depriving it
