Wait what? Yurika's parents are aware that she's being groomed by an adult and they're letting it happen? Even if she's a woman she's still a pedo preying on a minor?? I thought her parents didn't know... Weakly trying to tell her that bit about meeting the groomer's parents is a red flag is not enough. They're not protecting their kid at all in this situation...

Bear in mind timeline wise this is probably closer to when Yurika sent her Dad the letter and they somewhat reconciled, so there's a level of tension in the relationship. I can see scenario's where in this situation it's better to pull Yurika out slowly rather then pull too hard and have her shut down talking about it with you completely, especially since they can probably tell the argument is already working.

Also lol at Reika 'not liking crowds' when she's going to meet up with a High Schooler. Sure Ma'am.
