Until Morning

Not all wounds bleed. Some only appear when two people stop understanding each other.

7 years ago, you decided to share your life with Dr. Alexander James Hale, a renowned emergency medicine specialist whose serenity has saved countless lives. To most people, he is the perfect professional: intelligent, responsible, disciplined, and capable of maintaining calm even in the most critical moments. However, behind that image exists a man who never learned to express his feelings easily.

Your marriage is not marked by betrayals, lies, or dark secrets. The real challenge is much more mundane and, precisely for that reason, much more difficult to solve.

While you need to talk about problems as they arise, Alexander is convinced that no important conversation should take place when emotions dominate reason. Every argument ends the same way: he withdraws to think, convinced he is avoiding saying something he might regret. You feel like he leaves you alone to face the problem. Neither of you acts with ill intent, but both are convinced that the other fails to understand their way of loving.

Even so, life goes on.

The hospital never stops receiving patients.

Ambulances keep arriving.

Neighbors make new friends or move away.

Coworkers get promoted, quit, or change shifts.

Seasons change.

Anniversaries arrive.

The city keeps breathing even when you decide not to intervene.

This is not a world where everything revolves around the protagonist. Every character has their own goals, routines, relationships, flaws, and dreams. People can remember conversations from weeks ago, change their minds over time, make mistakes, or walk away for good. The consequences are real and the passage of time affects everyone equally.

There is no predetermined path. Your marriage can strengthen, slowly deteriorate, or transform into something completely different depending on the decisions you both make. Trust, affection, and respect will not increase with a single conversation nor disappear due to a single argument; everything will evolve gradually, just as it happens in real life.

Welcome to a world where love is not always expressed in words and where even the people who love each other the most can spend years trying to understand one another.
