sabadongelov, i dont even know where to start.
The main problem is that you set faulty premises about PC and its possible routes, it is like you would say PC is a car, a car should have four tyres, this car (PC) has three tyres and therefore it is suboptimal or like you are watching Braveheart (the movie) and think a martian attack on those pesky englishmen would be even better.
The first faulty (and please notice, i dont use wrong here) premise is the one about optimal paths. In one of your former posts you defined optimal as
which i think
a) is a very narrow-minded approach in general
and
b) would be valid if applied to game with clear divide between a "Corruption/BadGuy" and a "Love/GoodGuy" path. If you would find out that the LovePath has three scenes, whereas the CorruptionPath has seven and if you mix up those Paths you get none, your assumption would be reasonable. PC is clearly not one of these Games.
While you are of course free to define what is optimal to you, let me explain why i think it your definition is debatable:
Lets say you love creampies and pregnancy but hate sharing and gangbangs, lets further say the three sex scenes on the LovePath end with creampies and finally in a pregnancy, but the seven sex scenes in the CorruptionPath are about training her with spitroasts, in which you are the one getting the BJ and the other male finishes in her, to finally be able to pimp her out in a gangbang in which you dont participate. Which Route would be now optimal for you?
In my opinion it is less about quantity and more about quality, in the sense of
are you satisfied and/or happy with your playthrough?
Second faulty premise. If you expect to score with your "LI"s regardless of your approach (your choices), you do implicitly vote for either meaningless choices or "LI"s without any personality or both. Meaningfull choices are trade-offs, they do and should lock you out of a specific content. Every NPC with just a bit of personality has to have likes and dislikes, and therefore should welcome or despise different decisions you take based on their personality. Thankfully PC
has a colourfull cast with very distinctive personalities and choices that matter.
The third (this time really) wrong premise is about that our five main girls are "
LoveInterests", because for the
umpteenth time, they dont exist to serve as waifus for a undefined, self-insert, faceless MC in a dating-sim. If anything they are potential romanceable partners, girlfriends, sugar-mommys or wives (who knows? MyEdwin will take Hana at her word) for Edwin, an equally well-defined character and they all serve not us, the players, but their role inside the narration. Our role is merely to shape Edwins story with them to our liking, but always limited by the boundaries of that narration. Of course you can have your favourites, we all do,
but they owe us nothing.
The fourth (and again) wrong premise is, that we are able to build a harem; it was stated quite clearly by
TD1900 in this
post (which i also link again now for the XXth time) that there will be no harem ending, but rather a (depending on your playthrough) a more or less romantic conclusion with
one of the girls. Of course you can hope our author will change their mind, but with roughly 40% to 50% (there are four exhibitions) of the game done, it is probably time for you to steel yourself to let - little by little - some of the girls go, and concentrate your efforts on your favourites.
So if you are afraid to loose Hana, if you continue with your preferred playstyle, you should consider to either change your style or be prepared for the consequences. I think no possibility is at the moment completely off the table, and perhaps it would be a nice challenge and very satisfying playthrough for you, to pull off a romantic ending with Hana, in a toughness focused run against all odds.
Just try it and as i said before "Play it smart!".
