作词 : 細美武士
 作曲 : the HIATUS

 When the rain starts falling
 And the night gets dark enough
 Glow the living lights
 Of the fireflies
 End of rainy season
 Like a firefly
 When the light goes down
 All the tears are dried
 Then you go out on a rainy day
 Got harder than you thought it would be
 But you know that a sunny day
 is waiting just over the clouds today
 Here in town
 Deep inside
 In the dusty wind and heat
 Just a decent lie
 Everybody wants to know it
 Falling down
 Raindrops on the window stream sideways
 You mean a decent life
 Everybody wants to know it
 And you go out on a rainy day
 Got harder than you thought it would be
 But you know that a sunny day
 is waiting just over the clouds today
 Then you go out on a rainy day
 Got harder than you thought it would be
 But you know that a sunny day
 is waiting just over the clouds today
 And you go out on a rainy day
 Got harder than you thought it would be
 But you know that a sunny day
 is waiting just over the clouds today
 Then you go out on a rainy day
 Got harder than you thought it would be
 But you know that a sunny day
 is waiting just over the clouds today
