Oh no, not all the girls are virgins?!?! WHAT, this is preposterous!!! Those girls, who weren't in a relationship with the MC, who weren't even on the MC's radar yet, had sex with someone else? They didn't think to consider how it might make the MC feel, whom they had no relationship with yet whatsoever, how dare they?!?!

Btw, I just went to go check the context of what you were talking about, cause it's been a long time since I've seen the start of the game. He was a KID for both of those instances, and one of those was a completely optional scene, and the other was just Bredita being Bredita. They don't ever do anything with
other guys at least, once you become an adult. So one brief unavoidable scene, with a character that didn't even know the MC existed yet, and then an optional scene that you're not forced to see with Liliana where she was tricking Suntako to help Bredita, and of course this was
also when the MC was still a kid.
