Bài hát: Kimi Dattara - Happy Birthday

Zutto shitakatta koto wa tsuini
Kimi to wa dekinai mama tōtō owarimashita
Kadzuke ga kawaru koro ni tewotsunaide konbini e aruku
Watashi no tonari ni chigau hito ga iru yo
“itoshi teru” to iwa rete mo kimi janaikara
Watashi wa jōzu ni warau koto ga dekinai
Ichido mo sono kotoba o kuchi ni shinakatta kimi o kimi o
Watashi wa wasure rarezu ni iru yo
Atarashī koibito to dakiatte iru toki mo
Kisu o shite iru toki demo kimi o omoidasukara
Kimidattara kimidattara imakoko ni iru no ga
Kimidattara kimidattara don'nani yokatta ka
Kimidattara kimidattara watashi wa shiawasedattanoni
Son'na koto bakari kangaete shimau
Nagai jikan ga sugite mo naze
Kimi no koto bakari kangaete shimau no ka
Kokoro o yurushi kitta kimi no asagata no manazashi o
Ima demo oikakete yumemite iru yo
Atarashī koibito to tanjōbi sugoshite mo
Ryokō ni itte mo kimi o omoidasukara
Kimidattara kimidattara imakoko ni iru no ga
Kimidattara kimidattara don'nani yokatta ka
Kimidattara kimidattara watashi wa shiawasedattanoni
Son'na koto bakari kangaete shimau

Kimidattara kimidattara imakoko ni iru no ga
Kimidattara kimidattara don'nani yokatta ka
Kimidattara kimidattara nani demo aisetanoni na
