Welcome Back Emily

'That's when I'd realised that everything had changed while I was gone. It was like I'd been sent in a time machine two years forward, and I was two years behind everyone. I was still interested in the things they'd long forgotten. I should've let go of that old life, and welcomed the new. But I couldn't. The longer you cling onto something, the harder it is to forget about it, and If been clinging onto the memories of year eight for far too long.'

After Emily's Mum left, she was suddenly dragged out of her life. For two years until she came back, she desperately hoped she could see her friends again, holding onto the memories they had.
Her friends, in the meantime, were moving on. Having no idea why Emily never came back to school one day, they kept living their lives. Two years is enough time for them to change, and Emily never liked changes.
