I'll Wait For You (A Luke Hemmings Fanfiction)

Luke and the rest of the lads are leaving to go on a worldwide tour for 8 months.
Luke's girlfriend discovered she was pregnant with his child whilst he was on tour and hasn't had any contact with him at all.
She plans on surprising him, hoping to have a good outcome but is let down terribly when he accuses her of cheating on him.
Mackenzie then makes the decision of leaving Luke and bringing up her child on her own, but does it go to plan? Or does her feelings for Luke get the better of her?
