Toki wo modoshita sono koe
Totsuzen no phone amai tone
Sorekara bokura nandomo
"Meeru 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 owarenai
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 "kawaranai koto" docchi ga
Tsuyoi no darou
Hedateta toki no kanata de

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

Kore kara zutto kimi wa ex-girlfriend
Nanige ni fureta te ga setsunakute
Soba ni itai like a friend
Zurui keredo sore ga boku ni dekiru
Tatta hitotsu

Korekara zutto kimi wa ex-girlfriend
Tomodachi ja nai...koibito ja 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 owarenai
Kakusu kokoro 'til the end
Moshimo kimi ga naita nara ima demo
Dakishimetai
