I'm looking for this really lovely yaoi manga about two high schoolers that meet on a street line as they're walking home from school. They're both imagining different things will happen if they step off the line (a la the floor is lava). Please help me find this. I read it awhile ago and it was so sweet, I'd love to re-read.

I think its Life Senjou no Bokura maybe? I haven't actually read it,but the lines fit!

That's the one! Thanks so much!
