Why?

* koibitotachi wa totemo shiawasesou ni
Te wo tsunaide aruiteiru kara ne
Maru de subete no koto ga umaku
Itteru ka no you ni mieru yo ne
Hontou wa futari shika shiranai

Hajimete no denwa wa juwaki wo
Motsu te ga furueteita
Nikaime no denwa wa rusuden ni
Messeeji ga nokotteita
Nanakaime no denwa ga ima kara aou yo tte
Sonna futsuu no mainichi no naka hajimatta

* repeat

Jukkaime no denwa de futari
Tooku e dekaketa yo ne
Te wo tsunaide arukou to suru
Watashi ni tereteita yo ne
Sore kara nandome ka no yoru wo tobikoete
Kaeri no kuruma no naka de kiss wo shita yo ne
Shiroku kagayaku yuki ga totemo daisuki de
Sore demo kyonen wa hanareteita yo
Kotoshi no fuyu wa futari shite mireru kana
Sugoseru kana ieru kana
Ienakatta merry christmas wo

Kusuriyubi ni hikatta yubiwa wo ittai
Nando kurai hazusou to shita? watashitachi
Koibitotachi wa totemo shiawasesou ni
Te wo tsunaide aruiteiru kara ne
Maru de subete ga sou maru de nani mo kamo
Subete no koto ga umaku itteiru
Ka no youni mieru yo ne hontou no
Tokoro nante dare ni mo wakaranai
