Well, Lena is pushing hard for a threesome with Wade on the Ian cuck route, so it may happen soon.
I don't consider Ivy an antagonist. I see her more as a avenue for Lena's transformation. She doesn't force Lena to do anything, she just gives her opportunities. Along with Louise, she also serves as an example of an extreme of the relationship axis, much like Jeremy and Perry do with Ian. If I were to classify Ivy, she's the devil on Lena's shoulder.
I do think Seymour is the primary antagonist of the game just for the impact he has on the careers and potential futures of the protagonists. He has already cost Lena her job at the restaurant (if she hadn't lost it already) and her modeling gigs. It wouldn't surprise me if he is the one trying to buy the café. For Ian, he can drastically affect her future job prospects and his chances of winning the literary contest. Other characters such as Axel or Minerva serve more as personal antagonists.
I'll throw in my two cents from my experiences. The game is incredibly complex, and I can't claim to be an expert on every possible outcome. In order to get Louise in a threesome with either Ian or Mike, she either needs to have a threesome with Jeremy and Lena or break up with Jeremy and be sleeping with Lena. In order to get the threesome with Jeremy and Lena, Lena has to sneak into Louise's room and wake Jeremy up (plus obviously Louise and Jeremy can't break up); however, if you do this, Lena will refuse to date Ian, and they end up just hooking up. If they are just hooking up, I was unable to get the Ian/Lena/Louise threesome. I actually tried very hard to have a playthrough with both the Jeremy/Lena/Louise threesome and the Ian/Lena/Louise threesome but could never figure out the right combination of choices to make it work, if it is even possible (I really wanted one playthrough which set up a potential blow-up fight between Ian and Jeremy over Lena). It is possible that the reason for that is that the routes where Ian and Lena were just hooking up were also the routes where I had Ian pursue Cindy, Cherry, Minerva, Alison, or Emma seriously. It is possible choices made on those paths are what prevented the threesome. I did, however, succeed in obtaining both the Jeremy/Lena/Louise threesome and the Mike/Lena/Louise threesome where Lena convinced Louise to participate in the latter because of the former. Either way, it is possible for Louise to cheat.
I tend not to have Ian subscribe to Lena's SF if they're dating because it feels stalker-ish. Perhaps one of the most important aspects of a relationship is trust. If you can't trust the person you're dating, you probably shouldn't be dating them (even if I know as the player that Lena is, in fact, cheating on Ian. It's like checking up on your SO at work. One minor annoyance of mine is when Lena has a SF account, the responses from Ian are to think it's hot, get mad, or be insecure. I would have liked a "I don't care. I trust you." type of response.

Absolutely, but at least it involves honesty and open communication. It may be pure fantasy, but at least it has a sliver of plausibility. My biggest problem with most harem games is the MC sleeping with multiple girls behind their backs and them deciding to share because the MC has a magic cock. One of the worst tropes ever.
It's even simpler than that. Assuming you're not dating Cindy, you can get the Wade breaks up with Cindy outcome in three steps:
1) Go to the third photoshoot and don't get kicked out. It doesn't matter if you object to Axel touching Cindy's thigh or not.
2) After the photoshoot, ask Cindy "Do you really want to be with Wade?"
3) At the beach house, ask Wade "Are you even happy with her?"
Done. Wade has his epiphany and decides to dump Cindy.
Wouldn't Gollum say "my precious?"
I made a similar comment in my original post in this thread. Most of the core elements feel basically finished and just waiting on a resolution; however, many things have been introduced that just feel like their starting. It does make the game feel a bit bipolar. In some ways, if feels like it's just waiting on its conclusion. In others, it feels like it's only halfway done or just starting. If what you're saying is true, it makes complete sense.
Axel is also competitive and vindictive. Just letting him know that Perry is Ian's best friend might be enough to pique his interest.
It's ambiguous. Depending on route, though, I would say possibly to likely.
