That relationship is just wrong. I've read a lot of Harem stories, like not when they're in almost everything in Webnovel, some very good and some very forced but this one just doesn't fit. I read it and it feels bad. I like the 2 girls, they are very well written, but the way the situation unfolded was not good, I could have explained the whole situation to them or something. As this is very forced and does not fit. Same, great Fanfic author.
This just killed my interest in the novel, really not a fan of harems in this novels as it nearly never makes sense in the MC's context for it, it's cringe. Feels so forced, awkward and makes little sense for the characters in your novel. I could understand more if you wanted to go the harem route if you had Quinn interact with the two women quite a bit throughout the novel (far more than what happened.) and he ended up loving both but they interacted very little in the novel, with Ivy it sounds like there was a little sexual tension at best and considering how Quinn has been with flings this is just weird.
If people think this feels forced, then all I will say is that all relationships take effort to make it work. Even just a Couple takes a lot of work. A MĂ©nage e Trios even more. Most important is that all sides of any relationship needs to be open, defined and transparent, less one steps over the line. What the three of them did just now was to start off a healthy relationship between the three of them. The start is the most important.
