In my opinion, Rent-a-Girlfriend Season 4 was a very enjoyable and heartfelt season that showed good improvement in its story and pacing. The Hawaii arc added a fresh setting that made the characters more expressive and gave the story a new charm. The animation and direction were consistent, making every romantic and funny moment more meaningful and fun to watch. Chizuru’s softer side and Kazuya’s efforts to be more serious made their relationship feel more real and emotional. Overall, this season was touching, entertaining, and full of charm, reminding me why I enjoy the series so much.So I'll give it a 10/10 rating
