The reason we know this:

madfoxx:

Is love,

And this:

Is friendship,

is because this:

Is a man with a woman,

And this:

Is a man with a man,

So it seems obvious that these people:

Are in a heartbreaking love triangle,

While these people:

Are all happy as hell.

Sometimes an audience confuses

Romance

with

Bromance

and although

Heartbreak

might look similar to

Sulking

or

Intimacy

similar to

friendly comfortableness,

They are actually 

Very
Different

And it´s always easy

To tell
Them apart.

If you know how to

Spot
The signs.

The error is obvious really, 

These stories have nothing in common.

Can you guess why?

Do you want me to spell it out for you?

The reason that these stories are completely different is
that this one:

Is over now,

but this one

Has only just begun.
