Her.

She was his first, his last. His only.
They never intended for it to happen. Daniel and Rebecca had been friends for years, always able to laugh and chat merrily to each other, always looking out for one another.
The love was first kindled at a party in their first year of sixth form, drunken mistakes for some but a magical moment and connection for these two. Feelings that neither knew they could experience exploded to the surface.
They began to get closer, undeterred by the looks and whispers that they received as they strode the halls of the school together, first apart but soon holding hands. Something like this wasn't meant to be possible; she was the most popular girl in school and he was one of the "nobodies".
But that defines love in a way; an impossibility that soon becomes the best thing in your life, the sole reason behind your existence on this planet.

Daniel woke up in a start, confused and dazed by his surroundings. Had that all been a dream? He put his arm out across the bed and felt her, sleeping peacefully beside him. Daniel let out a sigh of relief and laid closer to her, let the steady rhythm of her heart gently ease him back into his slumber.
Life was perfect.
