Okashita tsumi no kazu ga sabishisa wo monogatatten dayo
Soshitara otona wa sore mite subete wo waruku iun daro?
Ienai mienai mitakumo nakunai? Dakara toberu hazu nai
Shouganaiccha shouganai kedo hontou wa sou jyanai

Wakatta youna furi de chikazuku kane no moujya
Tsume wo nobashita uso kakibito konna jidai dakara

I just keep it inside keep it inside kuchi ni wa dasenakute
I got something to hide something to hide iu no ga kowakute
I just keep it inside keep it inside dare mo shiranakute ii.
I got something to hide something to hide ore ni kamawanaide

Kakushitekita kazu ga akashingou wo arawashiten dayo
Uso wa dorobou no hajimari? Hatamata kanashisa no hajimari?
Wakaru? Shiranai?! Hanashi ni naranai! Sore jya hanashi takunai
Doushoumonaiccha doushoumonai kedo hontou wa sou jyanai

Wakatta you na furi de chikazuku yoku no mouja
Eri wo tateta tsumibukaki hito konna jidai dakara

I just keep it inside keep it inside kuchi ni wa dasenakute
I got something to hide something to hide iu no ga kowakute
I just keep it inside keep it inside dare mo shiranakute ii
I got something to hide something to hide ore ni kamawanaide

Hontou wa kotoba de oogoe de iitakute
Dareka shittete hoshikute hitori jya tsurakute

I just keep it inside keep it inside kono yo no naka dakara
I got something to hide something to hide obieru mainichi de
I just keep it inside keep it inside kakawaritaku mo nai
I got something to hide, but never put it aside kizuite kono kimochi
