In the evolving romantic comedy, "Rent-A-Girlfriend," Volume 3 starts as Kazuya Kinoshita finds himself in increasingly complex situations with his rental girlfriend, Chizuru Mizuhara. In the latest development, Kazuya's heroic actions at sea have added a new layer of complication to his decision to sever ties with Chizuru completely.

Kazuya, who initially rented Chizuru to alleviate his loneliness, has navigated through various awkward encounters and situations with her support. However, his recent maritime heroics have altered the dynamic between them. The stage is now set for a different kind of conversation, one that goes beyond the scripted interactions of a rental relationship.

Chizuru, who has consistently bailed Kazuya out of his cowardly ways and awkward moments, is now faced with a new reality. Kazuya's act of saving her life introduces a shift in the power dynamics and emotional stakes of their relationship. The narrative is likely to explore how Chizuru reacts to Kazuya's genuine display of courage and the impact it has on their connection.
