Ruined it with the cuck shit, good job bro.
Feel free to choose the route you want, the history of Midou is forged by the player.
If the only thing preventing her from being a bicycle is the MC stopping her, the player knows in their head that she's worthless. Unappealing.
It is not really the MC who stops it, you as a player choose how Midou acts or not. But well, I can understand that some people don't like it, it always happens.
