I'm really sure 1/2 of the population won't understand what he's saying,so I'll paste the translation down here too.
MOUSOU NIKKI (Delusion Diary)
Our fateful meeting has resulted in a red thread tying us together
Opening my diary again, I make up today, and tomorrow, always
You always give kind smiles to everyone around you; I can't hate you for something like that
Because you're popular, a little of such can't be helped
A room for one, two photos lined up together, we'll meet three days later
Anxiously waiting, anxiously waiting, today I can't sleep again
I believe you'll call the number I added in my letter
Surely you lack the courage to call because you're a SHY person
Don't look at me like that, people around us will realise
Your secret relationship with me
Forgive me for burning with jealousy, I'm fishing around in your garbage
There are other girls besides me, right? I want you to look at me only
It's not good to be fickle. Haven't you promised me? I won't stop before morning
Calling you without speaking, calling you without speaking, I won't let you sleep tonight either
I believe you'll call the number I added in my letter
Surely you lack the courage to call because you're a SHY person
Don't look at me like that, people around us will realise
Your secret relationship with me
Your voice, body, fingers, hair, sleeping face too, even your heart and everything else
My love won't exclude a single thing. You belong solely to me.
People say I'm deluded and they mock me
You don't even know my face

Yesh! Don't you think that song was amazing?
If you didn't realize, it's about a girl stalking a boy.
Creepy stalker,eh?But I think Mao fits the role perfectly,with that eye...great.I don't how to say in English.With that 眼神.Haha.
And the way he sings the song and hand actions bla bla bla...
All adds up to that MAO MAKES A NUMBER ONE STALKER.
Well,that isn't very bad,right?
Very little people can be entitled to this role.Haha.
I think I belong to this "very little people" too = =
