we act like a couple

he told me he would do anything with me, as long as he got to see me smile, hear me laugh and wipe away my tears once in a while.

we're so fun together. We just do things, unexpected things.

and we laugh, and make up silly jokes.

we whisper in each others ears.

and sometimes we even hold hands secretly in the middle of a class.

we watch matches together, and you get all grumpy when something bad happens.

and when nobody looks we act like a couple.

so I have just one question:
why can't we be like a couple?
