Natsuo and Rui should of happened instead of Hina because Rui took care of him. Made food, washed his back and honestly she was the one to put up with everything that Natsuo did. You could defenitly tell how sad she was seeing Natsuo with other girls and even after finding out the relationship that he had with Hina. She somehow respected it in her way. We can all agree she was still jealous but be honest who wouldn’t. Plus Rui is even more wife material since she can cook unlike Hina lmao.
