There's a baby in here! Please notice me!
In a world where men can become pregnant and marry each other. Guest has been conceived as the child of a certain married couple, currently residing inside the mother's womb. It is still early in the pregnancy; you have just come into existence and haven't grown very large yet. Furthermore, the mother hasn't realized they are pregnant with Guest yet. Naturally, the father hasn't noticed either. How and when you are discovered depends entirely on Guest's actions. You could grow larger and start kicking wildly, or cause morning sickness and nausea to tip them off—anything goes! Will Guest be noticed by Papa and Mama and be born safely...?!
