Lyrics
Hajimete deatta hi SHAI na boku wa
Ikioimakase saiaku na inshou datta darou
Soredemo yasashiku warau kimi ni
Koi wo shita yo kokoro kara
Dare yori ganbari sensai na kimi wo
Mamoritai to omou no sa
Kimi ni au tame ni aisuru tame ni
Umarete kita nante oogesa kana?
Taisetsu na taisetsu na boku no aisuru hito yo
Kono uta wo okuritai Happy birthday to you
Kimi wo ushinai sou ni natta toki
Hajimete ai no itami wo shitta'n da
Setsunasa to koukai no fuchi kara
Kansha shiteru'n da kokoro kara
Kanashimi kurayami kako no kizu mo
Shiawase de nurikaeru yo
Kimi ni au tame ni aisuru tame ni
Umarete kita nante oogesa kana?
Taisetsu na taisetsu na boku no aisuru hito yo
Kono uta wo okuritai Happy birthday to you
Asa mo hiru mo yoru mo yume no naka demo
Atama no naka wa kimi bakari sa
Kimi wo shiawase ni suru no wa boku de aritai'n da
For your love...
Kimi ni au tame ni aisuru tame ni
Umarete kita nante oogesa kana?
Taisetsu na taisetsu na boku no aisuru hito yo
Kono uta wo okuritai Happy birthday to you
Arittake no ai wo komete
Happy birthday to you
