I like harem stories with one boy and many girls. Reverse harem, on the other hand, is something I really don't like because sometimes the girl is slutty or she is forced into the situation.

I browse around and find that Tokoharusou e Youkoso is good. Apparently, there's reverse harem involving a girl, something I truly despise. I thought of avoiding it, but there seems to be a hero who will try to save the girl, which might be a positive counter point for me.

What I want to know from you who have read it is:
How terrible is the reverse harem?
Is she a slutty girl or is she forced into the situation?
Will the hero successfully rescue the girl from the reverse harem?
Will the girl join the hero's harem?

Short answers will be greatly appreciated, but thorough answers will earn great respect from me. I won't read the manga unless the story fit my taste. I'd rather be spoiled than be angry and heartbroken in the end.
