Well i wouldn't be so sure that there are no ways to do a harem, at least a partial one, without changing the given characters of the girls ..
BECAUSE... one of the most usual ways to reach a harem situation is when the girls are BISEXUAL and find some attraction towards each other. And since they fuck the same guy... you know what i mean ...
This is in fact the way it started with Lisa and Jade, right?
So let's look a little at what we have here and see if we can find signs or even proof of bisexuality by the girls..
1 - Jane .. "wants to settle down". OK, that may be, BUT Jane is also very much attracted to MC's sister Julia. While being "single" for such a long time inspite of how fuckin good looking and intelligent she is. May the reason for that also be that ...she is a little BI? Or more than a little? You bet! I know there should be no incest in this game (very much unfortunately) so a "pair" Jane-Julia on MC (the best of all imaginable) is not possible. But lets just remember that Jane is most probably BIsexual and then let's see.. who else ..
2 - Anna is most probably into her boss Catherine. Remember the scene when Anna and MC watched Catherine masturbatig in her office and Anna got so horny that she had to kiss the MC on the spot (since he was there and Catherine was behind a door)!
So Anna is probably also BIsexual.
3 - We have no sign that Catherine is also bisexual at this point but...she's good friends with.. Rosa, right? and about Rosa i have absolutely no doubt that she would fuck anything, men, women, horses... whatever.. It may be a little difficult to tenderly kiss a horse when he comes in, but if anybody can accomplish that, then Rosa!
So all that's needed at this point would be a nice sexy party or after concert party where all the ladies mentioned above would be present and , through the MC and/or because of the MC they could come together on a lesbian base.. which could then lead to many other things..
So that was .. "the ladies" .. Now let's see "the girls"..
- Lisa and Jade have already proven that they are clearly open to bisexuality (and to threesomes with MC).. at least occasionaly. This "triangle" is already forming in this last update and is probably going to develop more in time.
- Emma knows that the MC has a new GF but she also regrets that they separated and wants him back. She could chose to fight for him or.. to "share" him with Lisa.. (and with Jade lol) Hard to say how Lisa would react BUT since she is also more than "a little" into girls and Emma is a nice sexy girl, i would not exclude the possibility that she could also accept her in a possible mini-harem.
- Selina was indeed hurt by her friend when she jumped on the guy that Selina thought she likes. OK, BUT due to this "lesson of life" Selina is now a lot more open to sexuality and she does all the possible and impossible sexual things with the MC, so at this stage of her development i can not exclude a positive reaction to the idea of sharing the MC with other girls, which girls she may begin to like as .. girls, and maybe even asking in exchange that she should also be allowed to have other men.. (sorry but i can't exclude that either at this stage, she's her mother's daughter anyway ..
)
And Selina-Rosa... hard to get but, no longer imposible in such a case.
- And Nicole? Well Nicole is .. very "adaptable" isn't she..
Short said: everything's not lost, guys!
When there's a will, there is a way .. or several ways, you know
