Lyrics[]

Singer + Color

GUMI
Japanese (日本語歌詞) Romaji (ローマ字)
ハッピーシンセサイザ 君の 胸の奥まで happii shinsesaiza kimi no mune no oku made
届くようなメロディ 奏でるよ todoku youna merodi kanaderu yo

儚く散った淡い片思い hakanaku chitta awai kataomoi
笑い話だね 今となれば waraibanashi dane ima tonareba
見る物全て 輝いて見えた miru mono subete kagayaite mieta
あの日々がキレイに 笑ってるよ ano hibi ga kirei ni waratteru yo

我慢する事だけ 覚えなきゃいけないの? gaman suru koto dake oboe nakya ikenai no?
「大人になって頂戴ね?」 ならなくていいよ "otona ni natte choudai ne?" naranakute ii yo
知らない事ばかり 知らないなんて言えなくて shiranai koto bakari shiranai nante ienakute
「大変お似合いで」 ウソついてゴメンね "taihen oniai de" usotsuite gomen ne

ハッピーシンセサイザ 君の 胸の奥まで happii shinsesaiza kimi no mune no oku made
届くようなメロディ 奏でるよ todoku youna merodi kanaderu yo
つまらない「たてまえ」や ヤな事全部 tsumaranai "tatemae" ya ya na koto zenbu
消してあげるから この音で keshite ageru kara kono oto de

何の取り柄も無い 僕に唯一つ nan no torie mo nai boku ni tada hitotsu
少しだけど 出来る事 sukoshi da kedo dekiru koto
心躍らせる 飾らない 言葉 kokoro odoraseru kazaranai kotoba
電子音で伝えるよ denshion de tsutaeru yo

好きになる事 理屈なんかじゃなくて suki ni naru koto rikutsu nanka janakute
「こじつけ」なんて いらないんじゃない? "kojitsuke" nante iranainjanai?
時代のせいと 諦めたらそこまで jidai no sei to akirametara soko made
踏み出さなくちゃ 何も始まらない fumidasanakucha nanimo hajimaranai

「ゴメンね夜遅く 寝るところだったでしょ?」 "gomen ne yoru osoku neru tokoro datta desho?"
「驚いた 私もかけようとしてた」 "odoroita watashi mo kakeyou to shiteta"
心の裏側をくすぐられてるような kokoro no uragawa o kusugurareteru youna
惹かれあう2人に 幸せな音を hikareau futari ni shiawase na oto o

ハッピーシンセサイザ ほらね 楽しくなるよ happii shinsesaiza hora ne tanoshiku naru yo
涙拭うメロディ 奏でるよ namida nuguu merodi kanaderu yo
強がらなくたっていいんじゃない? 別に tsuyogaranakutatte iinjanai? betsu ni
自分に素直になればいい jibun ni sunao ni nareba ii

何の取り柄も無い 僕に唯一つ nan no torie mo nai boku ni tada hitotsu
少しだけど 出来る事 sukoshi da kedo dekiru koto
ちょっと照れるような 単純な気持ち chotto tereru youna tanjun na kimochi
電子音で伝えるよ denshion de tsutaeru yo
