Haha, I'm sorry T^T I completely understand why people want an Uriel route! For now, he will stay in the "Special" category. Making Uriel romanceable right now would actually spoil a lot about the overall story, because it would require certain events and encounters to happen much earlier than intended!
That being said, I'm not closing the door on the idea ๐ The thought of making an Uriel route has crossed my mind more than once XD If the demand becomes really strong, it's something I may consider in the future! <3
For now, don't worry, Uriel is definitely not being left aside! He is already part of the "Special" category, so there will be content with him :3 I can't say much more without spoiling things, but I hope you'll enjoy discovering his story ๐
