Note: "Aishiteiru Kara" is a solo song by Kamenashi Kazuya
from KAT-TUN's single "Love Yourself~Kimi ga kirai na Kimi ga suki"

Tatoeba moshi kono yoru boku ga kimi wo ushinatta toshitemo
Wasurenaiyo boku wa aishiteiru kara

mijikai kisu wo sotto kawasu to tsukiakari no naka ni
yawarakaku kanjiru tabi koboreru aijou

Waraigoe to ka kanashii kao mo takusan mitekita kedo
Hajimete miru sono sugata wa boku wo tomadowaseta

Kagi kakete sotto kokoro no naka ni
Arigatou sae mo kimi no kokoro ni todoketenakute

Hatenaku tsuzuku michi no naka ni kimi wa nani o omou no
Wasurenaide sono kokoro no soba ni sotto isasete

Kuyashii kimochi yami ni kakushite fuzaketeita ano koro
Taikutsu na otona ni naru yotei datta kedo

Kagi kaketeta kokoro sotto akete
Arigatou to iu kotoba kimi ni ima todoku ka na?

Hatenaku tsuzuku michi no naka ni kimi wa nani o omou no
Wasurenaide sono kokoro no soba ni sotto isasete

Kimi to no hibi sotto omoikaeshite wa
Hitori janai koto kimi ga boku ni oshiete kureta

Kimi ga kurushii toki wa dare yori mikata ni naru to kimeta
Wasurenaide boku wa kimi o aishite...

Tatoeba moshi kono yoru boku ga kimi o ushinatta toshitemo
Wasurenaiyo boku wa kimi o aishiteiru kara
Wasurenaide boku wa kimi o aishiteiru kara
