Lights, Camera, Role Play?

Renee Parr...she was the girlfriend of the heartthrob of OneDirection, Harry Styles. They did everything together, they shared thoughts, moments, and even kisses. Who knew that one little thing....one little moment...can change Harry's way of life. That event took place in a tragic car accident causing Renee to die. He was left devastated for a few days but then he regained his strength but not his courage. He pushes away everyone that comes his way, it was like he was totally different guy. He said that he'd never ever replace Renee. His manager was concerned about his recent doubtful behavior and assigns him with one of the most talented girls on the planet, Ariana Grande. She was the perfect fake-girlfriend to bring up his confidence. He straight up hates her guts but is there actually an empty spot in his heart for her? Can he get over the fear of those tragic memories with Renee? Will he finally leave the sorry past behind and move on to the present with his new love life.
