Comments of chapter undefined of Absolute Yin-Yang Desire System

hey author I wanted to ask if there is Yuri in the harem? cos I don't like that stuff.and is he gonna leave a harem member behind? will they be forgotten in the background and spoken of in just conversations while MC travels the world and most likely upper world's? will they ever meet again if left behind? and is his sister in the harem?You know I just dont like those novels in which the MC gets a harem member just to leave her at the end of arc never to be seen again or if they do then that'll be at the end of novel. i want the harem members to mean something and be involved in the story!
