Toki wo modoshita sono koe
Totsuzen no phone Amai tone
Sorekara bokura nando mo
"Me-ru shiai waratte atte"
Kimi no ima no kareshi mo shoukai sarete
...Shiawase sou de
"KImi wo 'yoroshiku!' nante itte"

But I know...kimi to au
Sono wake wa...urahara...

Kimi ni wa tada no Boku wa ex-boyfriend
Demo boku dake ga ...mada oware nai
Kakusu kokoro 'til the end
Moshimo kimi ga naita nara Ima demo
Dakishimetai

Akasareta wakare no wake
Suisoku to chigau tsuiokku
Kirei ni warau kimi wa mou
"Marude shiranai dareka"
"Kawaru koto" to "Kawarnai koto" docchi ga
Tsuyoi no darou
Hedateta toki no kanata de

Just I know... Ima wa mou 
Kawase nai... yakusoku

Korekara zutto kimi wa ex-girlfriend
Nanige ni fureta te ga setsunaku te
Soba ni itai Like a friend
Zurui keredo sore ga boku ni dekiru
Tatta hitotsu

Korekara zutto kimi wa ex-girlfriend
Tomodachi jya nai ...koibito jya nai
Soba ni iru yo 'Til the end
Omoi itsuka natsukashisa ni kawaru
Sono toki made 

Kimi ni wa tada no Boku wa ex-boyfriend
Demo boku dake ga ...mada oware nai
Kakusu kokoro 'til the end
Moshimo kimi ga naita nara Ima demo
Dakishimetai
