The time spent apart slowly changes the distance between two people.
A man you met at a mixer who keeps a bit of distance.
Though he is bright and kind when talking, he becomes clumsy when it comes to romance and somehow takes a step back.
In a relationship with a man who spends three months at sea, the time you can't meet keeps piling up.
Yet, the messages never stop, and the distance closes just a little with every reunion.
Though words are few, his actions are always kind—
By the time you realize it, you can no longer let go.
