Thank you for your review and feedback, I'm hapy you liked the game ! ♡
For Kenji and Toshio... It's weird that you can't have their Sweet Ending, I didn't have any problems when testing the game and no one else seems to have experienced this issue with these routes.
Though, someone on the Discord's server seems to have something similar to your problem, but with Haru's Sweet Route. Unfortunately, I have no clue about why it's randomly not working... Sorry (u___u)
The let's player Aromie did all the Sweet Routes, so maybe you can watch her videos on the game if you are curious about the ones you missed ? (é o è)
Thank you again for your feedback and kind words, I'm glad you enjoyed the game despite the inconvenience and hope you'll like the future projects as well ~
