Lyrics:

Ureshii koto attara sugu ni
Denwashite aitaku naru yo
Kimi ga irebe subete ga Make me SMILE
Sono egao taiyou dakara Kimi no nayami goto
Kyou wa kiite ageru yo
Dakedo kotchi ga itsumo
Genkitzuke rareteru Kimi wa kitto kitzuite inai keredo
Happy no oora furi maiteru Kanashii kotomo sukoshi kurai
Nai to mainichi wa tsumaranai
Nakitai toki wa hitobanjuu
Nee tsuki au kara
Hoshi mo aenai yoru datte
Kirei na asa ni tsuzuiteru
Kimi ga ireba tachimachi Make me SMILE
Umareteru yuuki no kakera Sora ga mabushikute hitomi sora shita no ni
Kimi wa makenai kurai
Hisashi ni kira meite Kimi to onaji jikan wo aruku tabi ni
Lucky ga motto fuete yuku yo Hitori ja nani mo dekinakute
Ashita to mienaku natte mo
Kimi no tame ni mune no man naka
Akete oku kara
Hoshi mo aenai yoru datte
Kirei na asa ni tsuzuiteru
Kimi ga ireba tachimachi Make me SMILE
Umareteru yuuki no kakera Kanashii kotomo sukoshi kurai
Nai to mainichi wa tsumaranai
Nakitai toki wa hitobanjuu
Nee tsuki au kara
Tanoshii koto wa wakeau hodo
Ookiku nareru kara fushigi
Kimi ga ireba subete ga Make me SMILE
Sono egao taiyou dakara

i feel like calling to see you at once
whenever you're there everything makes me smile
because your smile is my sunshinei'll lend an ear

bright so i turned my eyes away
but you're dazzling just as brilliant
in the sunlighteach time i spend with you

helpless all by yourself
and tomorrow is nowhere in sight
