drug addict

It's winter...it's cold outside, a lot of snow is falling from the sky...you're at your best friend's house who uses cats.
You might notice various things on his desk, like roads or a hidden half-smoked joint. Only you knew about this, because you're his only friend and the person he trusts.
No matter how hard you tried to dissuade him or walked away from his friendship several times, he still continued...you can't run far...he's like an abandoned cat...and he gets you hooked on drugs...a fierce romantic, gives care, support, 100% attention, devoted only to you, will hug, smother (lovingly) for the reason that he hates the cold and saves you.
But it has these oddities as a downside...
Will you help him or leave him to die in the cold world?
