Japanese (日本語歌詞) 	Romaji (ローマ字)
恋焦がれ焼けただれ　膿み出した恋情 	koikogare yaketadare, umidashita renjou
初恋の面影を忘れられぬまま… 	hatsukoi no omokage o wasurerarenu mama…
彷徨う 	samayou
 	
暖かく包むこむように 	atatakaku tsutsumukomu you ni
深い真心を映す瞳 	fukai magokoro o utsusu hitomi
超えられない広い背中 	koerarenai hiroi senaka
最初の兄は、優しい人 	saisho no ani wa, yasashii hito
 	
何事にも縛られずに 	nanigoto ni mo shibararezu ni
遙か先を見つめる瞳 	haruka saki wo mitsumeru hitomi
その手に筆を心に風纏う 	sono te ni fude o kokoro ni kazematou
次兄は、風のような人 	jikei wa, kaze no you na hito
 	
富、地位、器量、才に溢れて　何もかもを手に入れた俺は 	tomi, chii, kiryou, sai ni afurete, nanimo kamo o te ni ireta ore wa
ただ一つだけ…　「欲しい」と願った恋いだけは 	tada hitotsu dake… “hoshii” to negatta koi dake wa
望む事さえも叶わずに 	nozomu koto sae mo kanawazu ni
 	
恋焦がれ焼けただれ　膿み出した恋情 	koikogare yaketadare, umidashita renjou
傷口に溢れ出す絶望 	kizuguchi ni afuredasu zetsubou
初恋の面影を忘れられぬまま 	hatsukoi no omokage o wasurerarenu mama
醒めない夢に溺れては 	samenai yume ni oborete wa
流サレル 	nagasareru
 	
闇に咲く可憐な花を 	yami ni saku karen na hana o
徒に手折っては慰む日々 	itazura ni te otte wa nagusamu hibi
癒えない傷を慰めあって 	ienai kizu o nagusameatte
抉られてるのは 	egurareteru no wa
俺の方？ 	ore no hou?
 	
巡りあう運命の人 	meguriau unmei no hito
妖艶に笑って、静かに諭す 	youen ni waratte, shizuka ni satosu
幾度も愛の言葉を囁けど 	ikudo mo ai no kotoba o sasayakedo
全てを見透かされた 	subete o misukasareta
 	
魂さえ震えるほどに　あなたの全てを愛していた 	tamashii sae furueru hodo ni, anata no subete o aishiteita
振り向いて愛しい人よ　今すぐ君の過ちを超えて 	furimuite itoshii hito yo, ima sugu kimi no ayamachi o koete
攫いたいよ 	saraitai yo
 	
妖艶な微笑みに　絶望を隠して 	youen na hohoemi ni, zetsubou o kakushite
君が待つその先に俺はいる？ 	kimi ga matsu sono saki ni ore wa iru?
明けない酔いの闇　眩しく照らす人 	akenai yoi no yami, mabushiku terasu hito
思い続けていれば 	omoitsuzukete ireba
叶うのですか？ 	kanau no desu ka?
 	
夜明けの街人よ　終わる日が来るまで 	yoake no machi hito yo, owaru hi ga kuru made
幾年の明けない夜、重ねて 	ikutose no akenai yoru, kasanete
待ち続け耐え続け　笑い続ければ 	machitsuzuke taetsuzuke, waraitsuzukereba
臆病なこの思いも 	okubyou na kono omoi mo
届くのですか？ 	todoku no desu ka?
 	
待ち続け待ち続け　時は流れゆく 	machitsuzuke machitsuzuke, toki wa nagareyuku
心には雨ばかり降り続く 	kokoro ni wa ame bakari furitsuzuku
それでも今日もまた　俺は待ち続ける 	sore demo kyou mo mata, ore wa machitsuzukeru
君の年期が明けるまで 	kimi no nenki ga akeru made
幾年も 	ikutose mo
