I have written this

Girl, 'Hi. What are you doing here?'

Guy, 'I love you. I just want you to know that.'

He kisses her, then takes off.

She watches him go. And as she stands there, a feeling of relief pours over her, soon leaving her with a smile on her face as she heads back to her table.

Hi teachers. I have written this, is it ok? Is 'leaving' the correct word to use like this?
