He told her all the time how he loved her.

Not only in words, but in how he'd carefully watch her as she spoke, remembering little details that honestly didn't matter, but made all the difference to her; how he'd laugh at the worst jokes, even when she got them wrong, and shoot equally terrible quality ones right back; how he'd speak in calm cadence and hushed tones, and hold her heart gently when she was falling apart. He'd loved her for a few years now, and she knew.

He made sure she knew.

He loved her like the the wind loved the leaves; softly and playfully, yet with the potential of a tornado, powerful and strong. The latter is what frightened her the most, because she knew...

She loved him too.

Just as much.

And two storm systems moving towards each other never ended well. So she kept her love quiet, buried deep under the ground, hoping and praying to gods she didn't believe in, that there would never be a tectonic shift, cracking their world open and swallowing them whole.
