Aoi sora ga ureshikute
Fui ni kakedashite shimatta hito
Ame no hi ni tomodachi kara
Uchiakebanashi wo sareta hito
Katteta neko wo shinaseta hito
Inochi no owari wo shitte'ru hito
Kimi wa boku nanda
Boku wa kimi nanda

Umi wo mite-itara totsuzen ni
Tsuyoki ni natte sakenda hito
Mienai yakusoku wo shinjite
Hitasura tabi wo tsudzuke'ru hito
Un ga warui to boyaku hito
Nanika ga chigau to nayamu hito
Kimi wa boku nanda
Boku wa kimi nanda

Kawaii hito wo mamoritai
Yawai jibun ni sawaritai
Ima made ichido mo shitai koto no nai
Sayonara no iikata
Kuchi kara kobore ochita uta
Karada no uchigawa de hikaru genseki
Kimi wa boku nanda
Boku wa kimi nanda

Kore kara no koto kangae nagara
Itsu no ma ni ka nete shimatta toki
Kowarenai to omotte'ta mono ga
Akkenaku kowarechatta toki
Waza to warui koto wo shitai toki
Yuuyake ga mune ni haitta toki
Kimi wa boku nanda
Boku wa kimi nanda
