I have played it, and...
...very good! The setting of course is porntastic (school with special conditions for special kids with the permission to be inventive about your methods), it breaks the borders of what I came to expect here (a family with more than 2 daughters, a mc that is not shy about his goals while being competent, a loving wife that does not need to be corrupted to have sex, ...) and it shows a problem of the man with access to sex with young and willing women, who has children of its own, namely to draw a line. I want to stress that his love to his children is portrayed as sincere and parently. The interesting dynamic comes from the outside (Mika!), and is also not portrayed as pedophile, but as a girl with a crush and an adult noticing that.
There is a lot going on. Of course some is better drama, some is cheap, the whole story can go down the gutter easily (at least for my tastes), but it is fucking interesting, well written, with a bit of weeaboo and internet slang humor put in (does anybody really still use "over 9k"?), funny and strange and serious characters. And sexy, too. Do I sound like a fanboy? If the story continues to go like that , with the viewpoint of an adult, manipulative, morally flexible but not broken, competent man, I will be very happy to follow that. If it gets to a fuck everything that is legal with little resistance, I still take it, because I like the art. If he diddles the kids, I am out, because of not my thing.
Please, continue, I am intrigued.
