I think this game top tier. There is definitely a lot of work that goes into all the renders, and I very much enjoy the dom!MC, because most of those usually seem to relish in degrading their partners.
Great three dimensional characters (story arc wise), as well. Kudos to the dev. It's going to be a challenge to get that many LIs into the harem that by the time the later LIs' join the previous ones are still interesting and three dimensional, but I'm pretty sure the dev knows that. Also, we will have to have multiple arcs per character even post sexy time in order to tie up all the plot lines we already know of anyway.
I'm also actually curious how they're gonna manage with just that one bed. Even Sarah would probably be a tight fit (hurr hurr) at this point. They'd need to steal Diddy's party bed to get all the LIs in one place, and I don't think MC could afford enough bleach to risk using that thing.
In regards to Rachel:
I was actually surprised. I fully expected the spanking scene to result in the mesubuta route for Rachel via hentai logic. I was okay with it, too. What happened was actually quite pleasing from a storytelling perspective.
The MC might feel bad about Rachel crying, but he was fully aware that being alone with her (Hannah office scene) could become an absolute clusterfuck. Lucy also detests Rachel - as do Hannah and Allison.
Given MCs dislike, caution, and the fact that he is actually busy with things and very well taken care of there's no reason for him to go out of his way to deal with her. The only way a Rachel Redemption can happen IMO is, realistically, if her mother is effectively abusing her to the point where Lucy asks MC to help Rachel - or Lucy's mother returns with BS allegations and Rachel defends MC.
So my money is on one of those happening, probably the former. Much as Vicky is MCs wingman when adding girls to the harem (Cat) Lucy is the soul of that group.
Further random predictions: Brian's mother tracks down MC's mother and invites her over, Rachel's mother accuses MC of rape, Hannah's new habit of letting out her emotions by preemptively NTRing Brian as revenge will cause her to lose it with Brian in public at some point, Misaki will be the next waitress to get over her shyness, Cat is a romantic at heart and is falling so hard she'll dent the space-time continuum, Akari will be horny.
Also, if there isn't a Hannah/Cat threesome competition after that one office scene I'll be really sad.
