Kono Sekai de Ichiban No Shiawase Mono Ni Wa Suru Koto Nado Dekinai Kamo Shirenai Kedo.

Kanashi sōna boku no kokoro wa nani ka o motomete kawarihajimeta
Ano hi ni de aeta hitori dake o wasureru koto ga dekinaikara

Itsumo madede mo īyo
Kimi no koto dake o omoitsuzuketerukara
Itsumo madede mo īyo
Boku no kotodakara kimi to zutto issho ni irudarō

Kono sekai de ichiban no shiawase mono ni wa suru koto nado dekinai kamo shirenai kedo
Kono sekai de ichiban no shiawase mono da to omowaseru koto wa dekiruyo

You already have someone you love so much deep in your heart
I know, but still I can't help but tell you how I feel for you

Aa nando mo kowagatteta hitori ni naru no wo
Tsuyogatte mo kizu tsuite mo onajide

Even though you said no, it is not that easy for me to give up on you tonight

Konya mo kimi no koto sasaeteru no wa
Mada boku janakute modo kashiku narukedo

Whenever you're there close to me I see you fall in love again
Cause you give me the chance to be together with you now again
Boku ga dekiru koto nado sukunai kedo kimi o hitori ni wa shinaikara

Nan kai boku wa tomare kawatte mo wasurenai kara
Nan kai boku wa hitori da toshite mo kimi janai nara imi ga nai kara matteruno

Kono sekai de boku no ai ga tsutawaru hito wa nani mo iruka nado wakaranai kedo
Kono sekai de boku no ai ga tsutawaru
Hito wa kimi hitori dakega

Whenever you're there close to me I see you fall in love again
Cause you give me the chance to be together with you now again
Boku ga dekiru koto wa tada hitotsu dake aishiteru to kitsuzukeruyo
