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.
