Someone's been listening to Boku no Uchuu ni Kimi ga Iru too much. "Kimi no shiawase" means "your happiness". I own not the song nor the singer.
Kimi no Shiawase
If I may have one wish
Kimi no shiawase
I want your happiness
Even if it's not with me
Kimi no shiawase
I want your happiness
A long time ago
I believed we were
Meant to be
But it's not so
You are not her
And I'm not he
I can only protect you
Nothing more
I can't cause your delight
I can only direct you
From a distant shore
And dream of you at night
But I can always hope for
Kimi no shiawase
I want your happiness
I will always pray for
Kimi no shiawase
I want your happiness
I won't be the one to cause
Kimi no shiawase
I want your happiness
But that won't stop me from hoping he will
Kimi no shiawase
I want your happiness
If it can't be me
Kimi no shiawase
I want your happiness
Then it must be him
Kimi no shiawase
I want your happiness
So, crimson-girl, never forget
Kimi no shiawase
I want your happiness
It must be so
Kimi no shiawase
I want your happiness
You must be happy
Owari
Kimi no Shiawase
If I may have one wish
Kimi no shiawase
I want your happiness
Even if it's not with me
Kimi no shiawase
I want your happiness
A long time ago

But it's not so
You are not her
And I'm not he
I can only protect you
Nothing more
I can't cause your delight
I can only direct you
From a distant shore
And dream of you at night
But I can always hope for
Kimi no shiawase
I want your happiness
I will always pray for
Kimi no shiawase
I want your happiness
I won't be the one to cause
Kimi no shiawase
I want your happiness
But that won't stop me from hoping he will
Kimi no shiawase
I want your happiness
If it can't be me
Kimi no shiawase
I want your happiness
Then it must be him
Kimi no shiawase
I want your happiness
So, crimson-girl, never forget
Kimi no shiawase
I want your happiness
It must be so
Kimi no shiawase
I want your happiness
You must be happy
