Dearest [Name],

Tomorrow is a big day, and I've been thinking about you nonstop. I'm not talking about the existential dread of facing the void, though that's a real possibility. I'm talking about the fact that I saw you at the coffee shop, and your hair looked like it had been kissed by the sun. I'm talking about how much I want to be near you, to smell your scent, and to experience the warmth of your smile.

So, I've decided to make tomorrow a day to remember. I'll bring my A-game, my best coffee, and a decent chance of getting that promotion. Who knows, maybe we'll even find ourselves at the park, watching the sunset, and making plans for world domination... I mean, just a quiet evening stroll, but still.

Until then, know that you're on my mind, and in my heart. Don't forget to wear your best smile tomorrow, because I'll be the one smiling back at you.

Yours in love and anticipation,
  [Your Name]
