Boku Wa Shitteru

My Japanese level is pretty low, so please forgive any mistranslations:

I know, I know, I know. I know all about you, but you don't even know my name.

I know, I know, I know. You have an important person. And when you're together your face shows happiness.

I know, I know, I know. When you return from dates with that person, you come to my coffee shop at night. The coffee is my pride.

I can't tell you jokes to laugh at and I can't listen to you chat, but any time you want I can pour you some bitter coffee if you like it.

I know, I know, I know. When you came alone, your face looked lonely. "A little too bitter" but I know it's not the coffee.

What I really don't know about you is why I like you so much?

Have a cup of coffee, I can do that to make you feel good.

I know, I know, I know. You haven't come lately, but it's not because of the coffee's taste. The last time you came it was raining, but it wasn't raindrops rolling down your face.

I can't hold you on cold nights all the way until morning. But if you want to drink some bitter coffee, come again any time.

Whererver you are until then, cheer up.
