@Krowley maybe I’m overthinking things, but I’m not so sure about Okazaki’s win. She is going to win against her opponents, but not his heart.
I still can’t see Yabe saying “ok” to her just because she graduate. He obviously sees her charms, but at this point it ends here...can’t see any romantic feelings from him.
Maybe she’ll win, but after a timeskip of X years when she’ll come back to him as a proper adult.
