Known Bugs:
when you try to go to the shrine at the mountain at noon or night, it will teleport you to the neighborhood so you can't access the shrine. I have no idea why it does that and what triggers it, so i can't fix the bug, please bear with it T T
This isn't so much a bug per se, but my testers made me realize that getting either character's romantic routes are kinda difficult. So just be sure to shower them with gifts before their second events!
