Actually, although Ukyo's behavior in the other routes is pretty bonkers, I'd say his route is really good! It explains a lot about the plot, and I really loved his relationship with the Heroine. He's the best route in the game for me
If you're up for it sometime, I'd heavily recommend giving him a chance! The route has some pretty nice twists as well, and I think It would positively surprise you ;) if you're worried abou yandere behavior, I can say his route doesn't really go there, except maybe one single emotional moment, but the payoff is very good
