I remember making this because lowkey this is how I picture their relationship lmao.
Yap Sess (cw for abusive topics)
So o!Ranboo and o!Tubbo's relationship is semi-based off of a previous relationship I've had (I can eventually talk about it). For a preface, I headcanon Ranboo with BPD (specifically with it being undiagnosed slash unknown she has it because yeah (it's never been something she has thought about)).
When the two had gotten into a relationship, Ranboo had formed Tubbo as her FP and was unaware that any of the things she had been doing to him were actually driving him away. She sought out any way to force him to stay by her side - threatening to hurt him (and being physically abusive), mentally and emotionally abusive, etc.
Ranboo isn't MEANT to be a good person at first (mainly due to her trauma. She figured abuse is love and so, she abused the only person she loved.)
When Tubbo had inevitably broke up with her, it instead turned all her love for him into hate. She would constantly cause arguments with him in public because it was the only way she'd get Tubbo's focus on her and any attention from him was good attention (in her opinion. (This is not a good mindset.)). However, in private, she had vowed to herself that when Tubbo takes her back, she'd be just as loving as before - not knowing that her love had driven him away the first time (hence the first image).
Then, after months of them being broken up, Ranboo began learning from Tommy that, "Hey. Being abusive to your lover kinda isn't a good thing" and it was then, she knew she had to change if she ever wanted Tubbo back. She does her best to try and recover and become a better person with Tommy's help (there's no therapy so... Tommy is lowkey her therapist). He teaches her the right approach and while she's not perfect, she is much better than she is before.
Ranboo then becomes nicer to people (to the best of her ability. She still hates Sneeg with her entire body because she finds him annoying.) She has Tommy's words floating in her head to be nice as she talks to Niki and Jack. She has to remind herself that snapping at people isn't okay as she softens her tone around Slime or Scott. She begins doing better for herself - and sure she might slip up (recovery isn't an easy path) and say something a little too rude just because someone said something to upset her, she also knows she can apologize for it.
Now, I hear you asking, where does the second image come into play.
Well...
Tubbo probably would've never broken up with Ranboo in the first place if Tommy didn't pull Tubbo bafk and bring up the fact that if someone loved you, they wouldn't be hurting you as such. And sure, after some point, he began to push her buttons even further (he would talk on and on about how amazing his day was with Sneeg or his plans with Techno on a later date. Ranboo would threaten him because of it), he still loved her. He still loved her even if she had abused him (maybe it's the trauma. He doesn't know (it is.)). He continued to still love her even if they held arguments - it was the only way he could have her attention again.
When he heard she was starting to get better from her behavior (through Tommy of course), he - in private - vowed to himself that as soon as she's much more recovered (and not on the verge of abusing him the moment he mentions talking to one of his friends), they'll get back together (hence the second image).
At some point after a year or two of Ranboo recovering, the two do end up together (with Tommy too but this is mainly focused on beeduo's relationship but yes it is poly bench trio).
... also lowkey, these images were made with a roleplay in mind, but it also just lowkey fits how I headcanoned oBeeduo,,
This moment instantly gave me the idea of osmp! Ranboo being this spoiled royal brat who was kicked out of the end dimension because he was being stupid and now has to learn to live on his own.
