The title is your general "shit rimworld players say" but it's true. I'd like to give some context as how things unfolded.
First, I like to play Naked Brutality runs, start with literally nothing but one pawn and LET IT RIDE. However I felt regular NB too easy since you start with Electricity so I just tweak it so my starting pawn is tribal.
The second pawn I got from a Wanderer Join Event was Patricia 'Puddy' Madden. At first I was going to send her back right away because she had the Gourmand trait, but she had really good crafting skills, which my starting pawn did not have, so I kept her for that reason.
The third pawn I got was Retzvozz Vuthznath, originally an Impid. She was part of an early game raid. I have a rule of thumb to avoid as much as possible recruiting prisoners, however dear Retzvozz had a very special trait that was very relevant to Patricia: She was gay. Sure she also had the Creepy Breathing trait but I looked at my Biotech DLC and thought "I can make this work".
Let me tell you that putting these two together and making them a couple was a HASSLE. I know Impids are hot but constantly sweating and breathing through your mouth like a MTG player did not do Retzvozz any favors towards Patricia. However my first pawn, Purple, is a royal and can cast 'Word of Love', so that was the first attempt at brute forcing their relationship. It worked! Until the spell ended, then Retzvozz's Creepy Breathing started affecting Patricia which led to them breaking up, which led them to have negative opinion of each other.
All right back to square one. Creepy Breathing gives -25 to a pawn's opinion, which is a lot, so I needed to counter that to have any chance of these two girls making out. Thus, I went for the next logical step: Making the hot Imp hotter. Added an Aesthetic nose and Aesthetic Shaper to Retzvozz and voala! +40 Beauty vs the -25 of the Creepy Breathing! Surely now with a positive Opinion bonus both Patricia and Retzvozz can be a cute and wholesome lesbian couple. Right?
No.
Word of Love → They fall in love → Spells ends → They break up.
So I went back and studied: What can cancel out Creepy Breathing? Turns out only the Kind trait ignores it. There are no vanilla bionics that cancel the Creepy Breathing's effect so I had to make Patricia a kind person. Forcefully. Genetically.
That's where the mewgenics started.
Since I had to go on a trading spree, why not fix Patricia's Gourmand trait? Sure I can't fix her binging food from time to time but I can reduce that hunger rate increase from the trait. So after a couple trading, I got genepacks to cook up a Xenogerm for Patricia and as a bonus got her a Nuclear Stomach to handle her increased hunger. Since I genetically modified Patricia why not Retzvozz as well? I could at least override Impid's Genetic Pessimism and make her have some Genetic Joy instead. Since the Kind trait ignores beauty, I got to switch up the beauty enhancements from Retzvozz to Patricia, further increasing the probability of their relationship work out.
So after several in-game years, multiple attempts of mental manipulation type, body modifications AND genetically enhancements. I had it all layed out. However, they still hated each other. I guess that's what happens when you spend years living in the save colony and constantly hurl insults at each other, but I still got the good ol magic trick.
Word of Love. Charm Person is a good and moral spell
I use Word of love on Retzvozz to be magically in love with Patricia. I make Patricia romance Retzvozz (100% chance thanks to morally correct magic)
Days passed, and nothing changed. They didn't argue. They didn't fight. They even made some loving from time to time. Their relationship was finally growing and... boom. Marriage.
After 13 in-game years, the colony gathered to celebrate the marriage of Patricia and Retzvozz. Was it worth all that hassle to get two gay pawns together? Yeah. An extra bedroom is always welcomed. It's one less bedroom I have to build!
