The only candidates for the type of relationship vanilla lovers are looking for are Hana and Mina. If you are not ok with the LIs prostituting themselves (which is what the discussion seemed like it was originally about) then the remaining LIs are eliminated.
Yes, you are correct that the super vanilla players currently "only" have Hana and Mina as love interests.
I do agree that although right now we cannot have the 'talk' with the carnations, they will eventually become LIs. I feel like the romance with Veronica is probably the easiest among the carnations followed by Felicia (she is married + a massive hedonist so it will require some convincing) followed by Rose (due to her having a kid).
Interesting ranking for the Carnations by you. In my opinion a romance with Felicia is the easiest. While her marriage is a problem, just look at the evening drive with Feli´s proposal. Esp. if you chose to go with her to the art exhibtion without any strings attached, it is easy to see that the MC and Felicia have a clicking connection.
Rosi would be next. Her marriage is no problem, snce the piece of filth her husband is abandoned her into the crappy situation she is in. But from her personality we see currently and some other things, I think it more probable that at the end of the game they part ways on friendly terms.
Veronica I see as the least probable LI. She distinctly, even on very high realtions, told the MC that once the month is over she would prefer to never see him again outside his training at her gym. That is quite a hurdle to take.
Kat is a psycho and even in the endings I dont see her throwing away her marriage/reputation to be with some college kid. I think they will simply continue to fuck in the club. Edwin on the evil path might not be too interested in relationships/love anyway.
I define love interest as a person you will have a marriage or marriagelike relationship with. So Kath keeping her marriage while shaking it up with "bad" Edwin is definitely possible.
I would be very surprised if Sophia and Dalia are going to be actual LIs.
It would be really great if they become love interests! So please
TD1900 , if it is a thought option by you to make Dalia and/or Sophia datable love interests, please do so!
Those two would be great "against the flow" LIs.
From what we know from the character data and gameplay Dalia is a nice and indeed intelligent woman, who knows how to be delicate and when needed forceful. The only "conventional flaw" this Latina lady has is she is/was a prostitute, depending under what circumstances you get together. A man looking beyond her (former) occupation can make quite a catch.
In the case of Doctor Sophia Lundgren, she is the special one among the possible love interests! A brilliant mind, eccentric, cold and calculating, worming your way into her heart would be quite a challenge and a bit different from pursuing the other LIs! But as we see in game, the MC and Sophia, cardcarrying members of the Nerd Squad, connect quite well together and even better than Edwin thought would happen. If we play it right, we end the current game version on good terms with Sophia and her private phone number (for emergencies, but if it will become possible to date her, this might be just the beginning).
