Boundary.

Strangers → Acquaintance → Friends → Best friends → Lovers → Strangers

That’s how it goes, isn’t it?

I know where we are now. I do. And I would never cross that line and I hope you would do the same. I’d appreciate that.

Trust me, 

being friends is better than being lovers.

Let's not cross that line.

你的世界没有我 也许更辽阔
