Hiding something behind that smile

I really love your style but sometimes I think you’re hiding something behind that smile
Should we try? Sign up for a trial?
When I get lonely your number, I dial
You want to know when was the last I trusted someone? It’s been a while
I love being around you because the vibe is never hostile
 
With our love we can write a romantic novel
Or it can become a horror story, all the feelings get bottled
When we get into a fight, my mind wants to travel
You’re a sweetheart when you’re smiling
But when the smile goes away, I can feel the heat from the lava
