That was really sweet.
I really really like the main character. Her personality is exactly my type of person I like to play. Plus she is strong (actually strong and capable and sound in mind) too and her hairstyle is both pretty and practical. I always give these type of hairstyle to my characters in RPGs.
I think the alchmist knew that these two people were lonely and brought them together because of it.
Another thing that stuck out to me was the scene with the bandits at the waterfall. Normally when a character like Urbriel reacts like that I want to yeet them into the sun. It's mostly (japanese) otome MCs "McPure'n Sweet" who do that and it comes off always as the cheesiest most ungrateful, naive, ignorant drivel that makes me want to snatch them up and throw them off a cliff (looking at you, time/isekai traveller MC-chan, who ends up in times of war). It's like the don't live in reality and never really were part of human society. Like do they not watch any news and how did they manage to get through their history lessons in school? But in this case it makes perfect sense for someone like Ubriel and it was properly set up and resolved.
Edit: Oh and it was cool to see that the Ubriel/Ysra were just a part of the mystery, not the sole savior. Makes it more realistic for them to experience their small town bliss, in comparison to being the "hero" who solves all the the mysteries.
