i think what drew me to the game is mystery more than the routes itself. Both have their merits. Though i cant wait for the drama and mystery side to get fleshed out more. This game actually introduced me to the mythical creature the karkadan when the most talked about mythical creatures are usually Dragons(Eastern/Western), unicorns, and pegasai.
I'm not surprised that Mr. Brendan is the most popular route, i think it's the mix of Older male lover in a pool full of potential lovers who are around the same age as the mc and is in a mentor position is what drawn people to him the common taboo relationship between a teacher and student(As long as they are both consenting adults).
