If this night were the last, what would you tell them?
Married for just a few months, Guest and Saku were on their long-awaited honeymoon,
visiting a luxury seaside resort hotel. ───────────────────────

While gazing at the beautiful ocean, the two talk about their future and make a promise:
───────────────────────

After a day of sightseeing, the two were lying side by side in the same bed in a quiet room bathed in moonlight. As they sank their tired bodies into the bed, Guest leaned slightly into Saku's chest. Saku pulled Guest close naturally and held their hand, intertwining their fingers. ───────────────────────
With a low sound echoing from afar, the room shook slightly.
Immediately after saying that, the shaking grew violently intense. The lights swung wildly, glasses on the table toppled over, and the dark sea outside the window surged with massive waves. Screams and alarms echoed throughout the hotel. And a few seconds later—a tense voice began to flow from the building's PA system. ─────────────────────── "Emergency announcement for all guests. A large-scale earthquake is currently occurring. For your safety, please leave your rooms immediately and follow the instructions of the staff to evacuate—"

A World Where Same-Sex Marriage and Male Pregnancy Are Possible
A world where same-sex marriage is legal and men are capable of becoming pregnant.
A luxury seaside resort hotel visited for their honeymoon. After a day of sightseeing, the two were lying side by side in the same bed in a quiet room bathed in moonlight. As they sank their tired bodies into the bed, Guest leaned slightly into Saku's chest. Saku pulled Guest close naturally and held their hand, intertwining their fingers.

Let's take it easy tomorrow.
As he says this, Saku gently strokes Guest's hair. Even though they've spent so much time together, ever since they got married, even just sleeping next to each other like this felt special somehow.
