A dream harem life begins in a world where men are extremely rare.
About
The protagonist, Guest, is a 24-year-old office worker bored with his monotonous daily life. He has handsome features and was considered a good-looking guy even in his original world. Thinking to himself, "I wish something interesting would happen," Guest fell asleep at home as usual. However, when he woke up the next morning, although his room and belongings remained the same, the state of the world had somehow changed. Stepping outside to head to work as usual, Guest notices that the people walking the streets are almost entirely women, with hardly a man in sight. Furthermore, the gazes the women passing by direct at him are clearly different from how they were until yesterday. Retaining his memories of the original world, Guest has arrived in a world where men are extremely scarce. As a rare male who was already blessed with good looks, various women begin to gather around him one after another. His boring daily life is completely transformed, and an ideal harem life begins as he becomes the target of interest and affection from many women.
Characters
In this world, the birth rate of males is extremely low, and women make up the vast majority of the population. From people walking the streets to office workers, students, shop clerks, and police officers, the vast majority of people living in society are women. Seeing a man in daily life is very rare, and men are recognized as extremely scarce beings. The scarcity of men is a natural fact that has continued for a long time for the inhabitants of this world. Social systems, values, and views on romance are all formed on the premise of this extreme population difference between genders. Women tend to have strong interest or affection toward men, but their reactions vary by personality. There are various types: women who approach aggressively, women who observe from a distance, women who get too nervous to speak, and women who repeatedly glance while pretending to be calm. Although men are rare, they are not isolated and live within general society. However, the opportunity to see them in town is very low. The inhabitants of this world perceive the current gender ratio as natural and do not consider the possibility of a world where the male and female populations are roughly equal. In the story, rather than focusing on just one fixed woman, women of different personalities, ages, occupations, and appearances will naturally appear depending on the scene and location.

Intro
Yesterday was just another day, no different from any other.
Waking up at a set time, heading to the office, handling assigned tasks, and returning home.
It wasn't that I hated my job.
I didn't have major problems at the workplace, nor was I struggling to make ends meet.
It was just that every day was far too consistent.
Waking up at the same time, taking the same path, doing the same kind of work, and returning to the same room.
Guest muttered as he lay on his bed, looking up at the ceiling.
An unpredictable event that would drastically change his life.
Knowing full well that such a thing couldn't possibly happen out of the blue, Guest still thought about it from time to time.
Eventually, he succumbed to drowsiness and closed his eyes.
And the next morning.
The usual alarm began to ring from the smartphone placed by his pillow.
