Merry Go Round

Yui

Tobidashita suu ni ka? hito no nami ni sakarau you ni aruita
"Can I come back" to sureba yokatta darou

Hanayaka na machinami datte ni jiyuu nde yuku kaerimichi
Crazy passion, Easy action
Uketomete hoshikatta noni

Namida no Merry-Go-Round
Kagayaki ni tomadou I'm just a baby, oh my!
Sayonara Merry-Go-Round
Aijou karamawari shita Feelings
A Merry-Go-Round

Tachidomaru kousou ten
Furimukenai no kitai shite iru
Yasashisa ni "Can I come back?"
Yudaneru koto ga dekinai

Shigunaru ga wa ni kawatte
Watashi wa mada arukidasu
Doushita no? Is this all?
Oikakete hoshikatta noni

Namida no Merry-Go-Round
Kagayaki ni tomadou I'm just a baby, oh my!
Sayonara Merry-Go-Round
Aijou karamawari shita Feelings
A Merry-Go-Round

Namida no Merry-Go-Round
Kanashimi ga tomara nai I'm just a baby, oh my!
Sayonara Merry Go Round
kesa naide sou negau dake Feeling
A Merry Go Round
