Rent-A-Girlfriend Season 4 Episode 10 sub

Rent-A-Girlfriend Season 4 continues the story of Kazuya and Chizuru as they navigate their fake relationship, with a central focus on the dramatic "Hawaiians Arc". Following the successful crowdfunding of Chizuru's movie, Kazuya prepares to confess his feelings, but the situation is complicated by Ruka's aggressive pursuit and Mami's new scheming.
Plot highlights
The Hawaiians trip: The season is defined by a two-night family trip to Spa Resort Hawaiians, a holiday Kazuya's family takes every year. The trip becomes chaotic when not only Chizuru is present as Kazuya's "girlfriend," but his ex, Mami, also crashes the vacation.
Kazuya's resolve: Kazuya plans to use the trip as the perfect setting to confess his genuine feelings to Chizuru. He and Chizuru even have a close moment on a water slide, after which Chizuru's bikini top slips off, causing an embarrassing scramble for Kazuya to find it.
Mami's eavesdropping: Mami, who has been actively trying to sabotage the fake relationship, secretly follows Kazuya's mother and overhears a conversation with Chizuru.
Ruka's advances: Ruka also tags along on the trip and becomes more aggressive in her efforts to make Kazuya hers. At one point, she sleeps in the same room as Kazuya and Chizuru.
Chizuru's mixed signals: Despite the escalating chaos, Chizuru begins to show more genuine affection toward Kazuya. After they share some time alone, she offers him a discount on her rental services and thanks him for inviting her on the trip.
Confession and consequences: Kazuya successfully confesses his love to Chizuru during the trip. In response, Chizuru kisses Kazuya in front of everyone, including Mami, to make a statement that their relationship is real. In a later conversation, however, Chizuru tells Kazuya she still can't officially be with him, despite admitting her feelings. She explains that her inner conflict and life circumstances, including her career as a rental girlfriend, prevent her from starting a real relationship.
Outcome and moving forward
A confusing rejection: Chizuru's apology leaves Kazuya devastated. Despite admitting she has feelings for him, she says it's not enough to abandon her current life for a relationship.
Future uncertainty: As the season concludes, Kazuya is left grappling with the rejection, while Chizuru struggles with her fear of vulnerability. The anime ends with the relationship in a state of flux and uncertainty.
