He happens to be ; ;

He happens to be on my mind all the time.

He happens to be the only one i dream about.

He happens to be the one i talk to on the phone 24/7.

He happens to be the person i think of
when i hear a slow song.

He happens to be the one who always makes me smile.

He happens to be what i always wanted.

He happens to be the perfect one for me.

Now i just have one question,

[ I ] happen to be what to him?
