I literally made an account so I could comment here.
The secret route is the best honestly. I was more surprised that they r blood related, coz usually if there is brother/sister relationship in otome they r usually not related. I was expecting him to say "oh you know we r not even related", that would ruin the whole impression from the route. It could be more better and emotional, also dramatic, the part that touched me when he was talking about his childhood. But I am already happy with you putting this route there. I want to say thank you so much for that. His connection was actually very noticeable when I was playing other routes. Especially, in Sofia's route when he wanted to marry Sofia so she could stay with MC.
thank you! wish more games had routes like this
