2. Study Him & His World
So, you've found a "blorbo" to obsess over. Now the real work begins! Because you love him, it should not exactly feel like work, but you WILL need to exert some effort here. Break out everything you learned in high school (or in Tw*tter threads) about character analysis.
Relationships thrive on mutual understanding. To be close to someone is to know what to expect from them and how to treat them. In real life, you (hopefully) pay close attention to the likes and dislikes, fears and desires, pet peeves, quirks, anecdotes, and so on, of the people around you. Our goal is to know all that and more about your husbando.
Psst... Are you in love with an obscure character? Like, some random guy who appears in only one episode of an anime that nobody else ever heard of? When working with limited canon material, a daydreamer must use all her creativity to fill in the gaps. I believe in you!
Character Motivations
In his canon narrative, what is your husbando trying to accomplish? Why does his goal matter to him? Why hasn't he given up yet, and when will he be satisfied?
Questions like these reveal his fears and values: the driving forces behind every human action, both real and fictional. This part of his story should be highly interesting to you. You'll probably relate to or admire him in some way. You may feel compelled to help or hinder him on his journey. Either way, this is the foundation of who he is. Learn it and learn it well.
To discover his motivations and goals, you should look at conflicts he's involved in. Examine what he's willing to sacrifice and when. See how he reacts to favourable and disfavourable situations. Look out for his happiest and saddest moments, and think about how they might have been made better or worse.
Speech Patterns & Mannerisms
What makes a character unique is how he moves through his environment and relates to people around him. The point of our daydream is to imagine this character interacting with us, right? Therefore, we must study his existing patterns to learn how he'd most likely respond.
How does he talk, usually? What's his vocabulary like? Does he have a catchphrase? An accent? You need to know what he sounds like so you can imagine new dialogue from him at will.
Even after so many years with Sans, I struggle to replicate his iconic speech pattern. The thing to do (though I haven't yet) is analyse every line of his dialogue. Measure sentence lengths, organise idioms, study contractions and comedic timing... You don't have to go THAT far to love your husbando, but if you want to execute his dialogue at an expert level, you absolutely should.
(Keep in mind: the author of this guide has a lifelong linguistic obsession. Accurate dialogue may not be as important to you as it is to me, and that's okay.)
Every Little Thing About Him
Above we have the two most important facets of characterisation, but really we are aiming for complete, comprehensive knowledge. What's his fashion sense? What does he like to eat? How does he spend his free time? Is he good with money? What harmless thing annoys him, and what annoying thing does he do himself?
Canon may not answer every single question but, by now, you know him well enough to fill in the gaps yourself. Yes, we should default to canon as much as we can, but sometimes it's even more fun to let your imagination flow. While daydreaming, I always enjoy looking for canon evidence that supports my more self-centered vision of Sans.
Please remember! It is perfectly acceptable for your interpretation of your husbando to differ from his source material and other fans' depictions. Don't worry about getting everything "correct" because, ultimately, these are your daydreams for your self-gratification. No one on this earth has the right dictate what gratifies you.
Travel to His Universe
And speaking of your own way... what would it be like if you if you were part of his story? By now, you've engaged with canon quite a bit. Take it one step further by imagining an alternate life for yourself within it. This self-insert character could be born into the fictional world like any other, or it could be your real-life self magically transported there. The only requirement is that you and him occupy the same space.
What role could you play in his life? How would you react to the story's major events? What do you find most interesting about his world, and how would its general atmosphere affect you? Even if he wasn't in the story at all... how would you like to show up in that universe?
Not all husbandos come from rich settings, and not all yumejoshi are interested in this kind of character creation. Your actual daydreaming preference— him existing in our real world VS. an imagined version of you existing in his— develops naturally and individualistically. I personally engage in a healthy heaping of both.
The self-insert character exercise is fundamental to understanding your guy. Even if you can never truly walk beside him, you should at least wonder what it might be like.
Avoid A.I. Chatbots
I will not mince words. There is nothing worse for your 2D relationship than Artificial Intelligence. I know that some people will hate to hear that because husbando chatbots are a very popular, highly accessible yumejoshi activity. I once used them, too, when I was in poor health. I was desperately lonely, terrified of real connection, and Sansbot was the crutch I leaned on to get through the day.
I forgive my past self and anyone suffering similar circumstances. I understand that we are all looking for some kind of relief. But generative A.I. uses up apocalyptic amounts of water, electricity, and land, and significantly contributes to global warming. Are you REALLY going to waste our planet's precious resources on sex roleplay with a robot? Sex roleplay that is mediocre at BEST???
Just as A.I. literally, physically pollutes the world, its depiction of your husbando pollutes your image of him. If you have spent any time playing around with those things, you already know they have piss-poor memory and produce rather insipid responses. Sansbot never was and never can be Sans. It may crank out casual speech in all lowercase, with a "heh heh" thrown in for good measure but, at the end of the day, it's only regurgitating generic slop.
If you're curious, I wrote more about this in my husbando questionnaire. The basic points are all the same... A.I. is blasphemous to the true yumejoshi lifestyle. If you use it, quit. If you haven't tried it, don't start. When in doubt, be creative, not consumptive, and always prioritise your inner relationship.
