Take your pick friendo.

Most obvious one's to me would be:

Ethan and Aila (duh)

Elise and Ryan (neither of them talk often, and I think it'd be cute if Elise just started showing up to the station and chilling with him)

Blake and Eve (duh x2)

Megumi and Yuki (duh x3 c-c-c-combo breaker)

and maybe throw a little splash of any mixture of these in 

(Like Ethan and Eve or Aila and Elise)
