Review Detail of CHAOS_FOOLISH in Overpowered Villain Returnee in the Apocalypse - System is for Losers

Hello author! I would like to ask some questions, if possible, please answer... they are as follows: I would like to know if there is harem in the work, I would like to know if there is ntr or yuri in the work (I hope not), I would also like to know if there would be yanderes among the harem... and the last question, and if the mc really loves the girls, he doesn't just use them and discard them... if you can, please answer!
