LYRICS:

Dakara ima ai ni yuku 
So kimetanda 
Poketto no kono kyoku wo 
kimi ni kikasetai 

Sotto boryu-mu wo agete 
Tashikamete mitayo 

Oh Good-bye Days 
Ima, kawaru ki ga suru 
Kinou made ni So Long 
Kakko yokunai 
Yasashisa ga soba ni aru kara 
La la la la love with you 

Katahou no earphone wo 
Kimi ni watasu 
Yukkuri to nagare komu 
Kono shunkan 

Umaku aisete imasu ka? 
Tama ni mayou kedo 

Oh Good-bye Days 
Ima, kawari hajimeta 
Mune no oku 
All Right 
Kakko yokunai 
Yasashisa ga soba ni aru kara 
La la la la love with you 

Dekireba kanashii 
Omoi nante shitaku nai 
Demo yattekuru deshou, oh
Sono toki egao de 
"Yeah, Hello My Friend" nante sa 
Ieta nara ii noni 

Onaji uta wo 
Kuchizusamu toki 
Soba ni ite I Wish 
Kakko yokunai 
Yasashisa ni aeta yokatta yo 
La la la la good-bye days
