Find that out at one of the ending of HTA. They are immune to not falling for him if they watch but if they have sex with her that's another story. That image is from a farming sim I wanted to include in Magic Ring game as a mini game. Himawari was gonna be one of the bachelorette . Since it's scrapped used that image to take a jab at using AI to create image. I think it's mentioned when you interact with that image in college level.
The second question will be answered after HTA is complete.
