Kon'na ni hiroi chikyuujou no naka kara
Dou shite futari ga deatta n' darou

Kidzuite mireba anata wa tonari ni ite
Watashi wa nan' nimo mienaku natta

Don'na koto ga atte mo anata to wa kono mama
Kawarazu kurashite iru to shin'jite ita no

Itsu kara futari wa shaberikata made onaji
Kagami ni utsutta jibun' mitai ni

Shiawasesugiru to nan' de namida ga deru no
Shiawase no tsugi ni nani ga mieru no

Itsuka tsutaetakatta wake mo nai kanashisa
Mune no oku ni shimatta mama kotoba ni dekizu

BEN'CHI ni suwatta futatsu no kage wo tsuki ga
Yake ni betsubetsu ni terashidashiteta

Deai to wakare wa "TWIN" ni natta sadame (un'mei)
Wakatta toki kara kokoro wo kimeta

Aru hi tooi basho he hanarete shimatta mo
Sabishii nan'te omowanai datte watashi wa

Anata to onaji kuchiguse wo MANEnagara
Kagami ni mukatte waraikakeru yo

Anata wo mitsukete waraikakeru yo
