This is actually good, i kinda want to see more. By the way, the more I watch Holo animation, the more I kind of want to see when someone would try to make an animation of the same quality as Touhou's Summer Day Dream
Personally I like to see where this is going more. More often than not, someone who is toxic in their personal relationship would be toxic as well in their professional ones.
In cases like this, it's usually both parties are found to be equally scummy
I just want to say that a 16 years old flirting with 12-14 years old is like a high school student flirting with a grade schooler/middle schooler. It might not be illegal, but it's still kind of weird to me.
Also as you say, the moment screenshots are dropped is the moment that will make or break this accusation
