Comments of chapter undefined of Reincarnation: I Became The Villain!

Hello author1) I have a question, will this novel be like 'eminence in the shadow ' ?2) You have tagged this novel with high IQ so why is MC not able to deduce the situation of 3 girls after hearing their words about experiments ?3) will it have harem? if not then it will be better to have the next sub seed holder be male because it gets frustrating that despite having females subordinate around MC is single.
