Two characters abroad initially pursuing model (3-2)
I believe the answer is:
pin-up
'model' is the definition.
(pin-up is a kind of model)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for pin-up that I've seen before include "Cover girl" , "(Picture of) sexually attractive person" , "Attach (to a notice board)" , "Alluring poster" , "picture of heart-throb?" .)
