The Guy Who Prefers Being Alone

Kiriyama Yuuki is the kind of guy who seems like he’d be perfectly happy with just a corner seat in class, a part-time job, and a quiet life. He’s pretty withdrawn, rarely initiates conversation, and seems totally used to handling everything on his own. But that calm exterior? It didn’t just appear out of nowhere.

The setting isn't your typical modern-day world either. Because the male birth rate is plummeting, polygamy has become the norm, with men allowed up to ten wives. Now, that might sound like a harem lover’s paradise, but the story actually spends a lot of time on grounded school life and very ordinary relationships.

Harem Isn’t the Main Course

The most misleading part is actually the title. Looking at it, you might expect a protagonist who steps out his front door and finds a line of girls waiting for their turn. In reality, the early chapters focus more on the life of a loner and how Kiriyama Yuuki slowly finds himself pulled into social circles.

Instead of being introduced as new members of a harem, the female characters pop up through school, work, and daily life scenarios. That’s where the appeal lies—watching Kiriyama Yuuki transition from someone who wants to stay on the sidelines to someone who actually starts to care about people.

A Past Heavier Than It Looks

Kiriyama Yuuki isn't just a loner because he thinks being "cool and edgy" is a personality trait. His past involves a serious incident that changed how everyone looks at him and made him a target for bullying. This gives his isolation a much deeper, more grounded reason.

What’s interesting is that the story doesn't turn Kiriyama Yuuki into a constant mess of misery. He still goes to school, works his job, chats with people, and handles the little things in his day. These moments make him feel like a real person trying to live normally, even with a lot of baggage dragging behind him.

Relationships With a Personal Touch

The interactions are probably the easiest parts to get through. Some older characters enter Kiriyama Yuuki's life with clear roles, leading to scenes that are both sweet and a bit funny. Take the scene where an acquaintance suggests a fake marriage—it shows how the story loves creating drama out of very mundane, yet unexpected, situations.

• Kiriyama Yuuki remains central and typically observes everything with a calm attitude.
• He shares a bond with Yuki close enough that many daily interactions between them feel natural.
• Hinata acts as an adult figure involved in Kiriyama Yuuki's school life.
• Other female characters provide various paths for romantic development rather than just appearing as background figures.

The Good Stuff

• A protagonist with a reason to be a loner: Kiriyama Yuuki's past provides a real foundation for his personality, so he’s not just "cold" for the sake of it.
• A logical polygamy setting: The fact that society allows a harem because of a male shortage gives the world-building some internal logic.
• Relatable slice-of-life: School, part-time jobs, catching a cold, and short phone calls are all used effectively to bring characters together.
• Not reliant on power levels: The focus is on human relationships, making it feel quite different from your typical power-fantasy harem.

The Not-So-Good Stuff

• Inconsistent character behavior: Some readers feel that the way people react to the serious events in Kiriyama Yuuki's past doesn't always feel natural.
• Uneven pacing: Relationships sometimes move too fast, while some issues that deserve more depth are brushed over.
• The story stops at just 23 chapters, meaning many relationships and the whole polygamy concept haven't had a chance to fully develop.
• Some reviews complain about repetitive internal monologues and plot points that feel a bit too convenient.

What the Community Thinks

• Novel Updates: 4.2/5 with 151 ratings (checked on 02/10/2026).
• A group of readers really likes Kiriyama Yuuki for being a calm, collected loner and appreciates the logical explanation for the harem setting.
• On the flip side, many critics point out issues with character consistency, pacing, and societal reactions, arguing these flaws make the story less convincing.

Is It Worth Your Time?

With only 23 chapters and a long hiatus, this definitely isn't for those looking for a complete harem story to finish in one sitting. But if you're into school life stories with a loner lead, plenty of romantic tension, and a unique polygamy backdrop, the beginning still has enough charm to be worth a look.

In short: The story has a cool concept and Kiriyama Yuuki is a well-grounded lead, but the execution is a bit hit-or-miss, and stopping at chapter 23 leaves a lot of potential on the table.
