We Were Made To Love (larry stylinson)

Summary:

"Everything all sorted? Need help with the buckles? I know they're a bit tricky in this compartment."

The voice startles Louis out of his daze, and he turns toward the voice to let him know he figured it out. When he catches sight of the owner of the voice, though, his response dies in his throat. Whatever he had imagined the conductor of a children's train that rides around the shopping centre in Leeds would look like, this is certainly not it.

Leaning through the window, arms folded across the sill, is a green-eyed angel with cherry red lips stretched wide in a smile and dimples flirting in his cheeks. A black conductor's hat is the only confirmation that this is not some gorgeous stranger who's come to flirt with Louis through the window of a children's train, but is just a man doing his job.

[or, Harry drives a kiddie train in the shopping centre for the summer and is obsessed with babies, and Louis never stood a chance.]

So this is not my own story. Took it from A03 so its easier to read. Credit to supernope.
