The thing with kaede game, is that the game is a sequel to a NTR game.
Im also one of the people that were disappointed (i dont complain about it though) with the new game being netorase, let me explain:
In Daily Life, the plot is that the mc and fmc are expelled from school because they fought against the teacher sexual harassment, MC goes straight to working and after some hard times they manage to make a good life and marry each other. The MC gets in a coma, and as a ghost he watches the teacher coming back and the ntr happening with the wife. After he wakes up when he caught them in the teachers appartment, he completely breaks, FMC little sister, silent girl with strong personality, who had a crush on MC, finds him on the ground and also looks to the mirror of the apartment and see the affair. The teacher finds them watching him with the wife, goes out, and try to ntr the sister with the classic "If you want to save MC, take your sister place and i will let her go back to him". The little sister's (kaede) response to that is to kick the teacher in the balls and leave with the MC.
Then in the epilogue we read that MC spent years in depression but kaede was with him supporting him the entire time, until he finally gets over it and marry kaede, the woman who saved him from his misery. Then the last seconds of the game is a sort of preview that kaede will get ntrd in a new game.
Now, to add even more context, right after daily life and before kaede game, there was a new game that was about another side character from daily life with connection with what happened in the school, so another game was made with another character getting ntrd by the teacher.
Because of all that, i was expecting the teacher to be the ntr guy in kaede game too and was really excited for it. To me it would be the perfect NTR, after losing his carrer to him ( never graduated school), he loses his wife, gets healed by the little sister only for her to get seduced by the same guy again years later, that would be peak NTR to me, even more considering how the teacher failed to ntr her in Daily Life and then succeding this time and getting his revenge.
All of that, only so that in the end its netorase with a side char (to be fair this side char also ntrd the wife a little but its just not the same)
So yeah, kaede game will still problably be really good, im enjoying it so far and i a fan of SORAUE works, but im still really disappointed that its netorase
