[Verse 1]
Dear diary
Nemure nai yoru ni wa
Afureru tears
Osae te miageteru stars
Sō Why do we?
Kizutsuke au bakari de
What can I do? What can I do? dōka oshie te

[Pre-Hook]
You keep all my secrets
You know all my fears
You hear all my laughter
Donna toki mo

Dear diary
Kono sekai ni hikari o
Tada aisuru koto dake de
Let's make the world a better place
Dear diary
Kono te ni chikara o
Kanashimi o tsuyo sa ni kaeru yō ni
Oh please
Dear diary
[Verse 2]
Wasure rare nu hodo ni
Kurikaeshi
Mune shimetsukeru ano shīn
Why can't we
Wakariaeru no nara
How can I do? How can I do? dōka oshie te

[Pre-Hook]
You keep all my secrets
You know all my fears
You hear all my laughter

Kono negai o kanae te
Tada shinjiru koto dake de

Dear diary
Kono te ni chikara o

[Bridge]
Ore te shimai sō na my heart
Nidoto kire sō mo nai start
Should I, should I, should I still believe?
Dakedo ima kono omoi chain
Kirihanashi te try again
Yes I still believe
