As of December 2025, the manga series Kanojo, Okarishimasu, globally known as Rent-A-Girlfriend, is teetering on the edge of its conclusion, and the fan base is in a state of absolute chaos. The long-running romantic comedy has reached a critical juncture, with recent chapters sparking one of the biggest controversies in its history, leaving the ultimate "Rent a GF ending" hanging in a precarious balance.

The core question remains: After hundreds of chapters, will Kazuya Kinoshita and Chizuru Mizuhara finally move past their rental contract and become a genuine couple, or will the story deliver a devastating, unexpected twist? The latest plot developments have fueled intense speculation, with conflicting "leaks" and theories suggesting everything from a perfect romantic finale to a tragic, reputation-ruining rejection.

• Kazuya Kinoshita: The protagonist. A college student with low self-esteem who rents Chizuru after a bad breakup. His character arc revolves around his transition from a pathetic, indecisive young man to a genuinely supportive, if still awkward, individual who deeply loves Chizuru.
• Chizuru Mizuhara (Ichinose): The main heroine and professional "Rental Girlfriend." She is ambitious, dedicated to her acting career, and maintains a strict professional facade. Her internal struggle is balancing her professional role with her growing, genuine feelings for Kazuya.
• Mami Nanami: Kazuya’s ex-girlfriend and the primary antagonist. She is outwardly sweet but possesses a manipulative and complex personality. Her goal is often to sabotage Kazuya and Chizuru’s relationship, driven by her own unresolved feelings and jealousy.
• Ruka Sarashina: A self-proclaimed "temporary" girlfriend. She is energetic, possesses a heart condition that only Kazuya seems to affect positively, and aggressively pursues a real relationship with him, often complicating the main couple's progress.
• Sumi Sakurasawa: A shy, reserved Rental Girlfriend and a recurring character. She is a close friend and confidante to Kazuya, often helping him with his relationship troubles, though she harbors her own quiet feelings for him.

The Latest Manga Updates: The Confession and The Backlash

The tension surrounding the "Rent a GF ending" reached a fever pitch with the developments in the final arcs of the manga, specifically around Chapter 379 and Chapter 380.

Kazuya’s Breakthrough Moment

After hundreds of chapters of hesitation, internal monologue, and near-misses, Kazuya finally managed to deliver a full, heartfelt confession of his love to Chizuru. This moment was long-awaited by fans and signaled a massive, irreversible progression in the story. It was the culmination of years of character development, where Kazuya put his genuine feelings on the line, forcing Chizuru to confront the reality of their relationship.

Chizuru's Cryptic Response and The Fan Controversy

The real controversy began with Chizuru’s response. While one major fan-favorite moment suggests she finally confessed to being in love with him in Chapter 379, the overall reaction to the immediate aftermath has been mixed. Many fans feel that the plot, despite the major confession, has managed to "regress" yet again, preventing the final, decisive answer.

This feeling of stagnation, even after such a significant emotional climax, has led to a massive backlash. Fans are frustrated that the core relationship dilemma—will she stop being a rental girlfriend for him?—continues to be dragged out, leading to widespread criticism that the author, Reiji Miyajima, is intentionally delaying the inevitable conclusion for engagement purposes.

The 3 Most Controversial 'Rent a GF' Ending Theories

Given the current state of the manga—a major confession followed by an ambiguous, drawn-out reaction—three main theories dominate the discussion on how the Kanojo, Okarishimasu story will conclude.

1. The Happy Ever After Ending (The Author's Hint)

This is the conclusion most fans have waited for. In this scenario, Chizuru accepts Kazuya's confession, ending their rental contract and beginning a genuine, romantic relationship. The theory is supported by a significant rumor that the author, Reiji Miyajima, once mentioned in an interview that the manga would end with them officially becoming a couple. This ending would validate Kazuya's long struggle and give Chizuru the emotional stability she needs to pursue her acting dreams while having a partner. It’s the definitive "Redemption" ending for the series.

• Key Entities: Kazuya Kinoshita, Chizuru Mizuhara, The Grandparents, Wedding Bells.
• LSI Keywords: Relationship progression, definitive conclusion, romantic comedy trope.

2. The Tragic Rental Ending (The Infamous "Leak")

This is the most controversial and highly debated potential ending, which many fear will "ruin" the series' reputation. The theory, fueled by a widely circulated, unconfirmed "leak," suggests that Chizuru will ultimately reject Kazuya.

The supposed reason for the rejection is that Chizuru chooses to continue her life as a professional rental girlfriend, prioritizing her career and independence over a relationship with Kazuya. Kazuya is left heartbroken, and the series ends with them going their separate ways, perhaps with a time skip showing them living separate lives. This would be a deeply bittersweet, if not outright tragic, conclusion that emphasizes the professional boundary over personal feelings.

• Key Entities: Rental Girlfriend contract, rejection, tragic ending, character regression, Mami's influence.
• LSI Keywords: Bittersweet conclusion, fan outrage, controversial manga ending.

3. The Ambiguous Harem Ending

A less-discussed but still plausible ending involves an intentional ambiguity. The story might conclude with Kazuya and Chizuru sharing a kiss or a mutual understanding, but without an explicit "official couple" status. Alternatively, the author might choose a "harem" style ending, where Kazuya is left to choose between Chizuru, Ruka Sarashina, and Mami Nanami, or perhaps he ends up alone, finding peace and self-respect without a partner.

This ending would leave the door open for future spin-offs or sequels but would likely frustrate the majority of the fan base who have invested years in the Kazuya/Chizuru dynamic. It’s the "Engagement" ending, designed to keep the discourse alive indefinitely.

• Key Entities: Ruka Sarashina, Sumi Sakurasawa, Ambiguity, Time Skip, Author's choice.
• LSI Keywords: Open-ended finale, unresolved tension, future anime season.

Why the 'Rent a GF' Ending Matters So Much

The ultimate conclusion of Kanojo, Okarishimasu is more than just the end of a manga; it’s a commentary on modern romantic tropes and the concept of emotional honesty. The series has consistently explored themes of self-worth, the facade of professional relationships, and the difficulty of genuine communication.

If the final chapter delivers the long-awaited happy ending, it will serve as a powerful message about perseverance and the reward of supporting someone through their dreams. If, however, it opts for the tragic or ambiguous route, it risks solidifying the series' reputation as a story that prioritized drama and stagnation over meaningful character progression. The entire legacy of the Rent-A-Girlfriend franchise, including the highly anticipated 2025 anime season, rests on how Reiji Miyajima chooses to resolve the relationship between Kazuya Kinoshita and Chizuru Mizuhara.
