How they first met: Dawn grew fond of spending time in the Distortion World after she initially visited it while facing down Team Galactic, enjoying just getting away from it all to a quiet place where she knew could be alone. She would usually bring a Thermos of tea and a book and find some nice spot by an inverted waterfall and read. It was during one of these visits that the even that caused the Legendary pokémon to revert to their human forms (if they had one) occurred. Now, Dawn was used to occasionally encountering Giratina on her visits to their realm but the two usually just left each other alone. So, when she saw Giratina heading her way and seeming to be in distress, Dawn knew something big was up. Giratina barely made it to her platform before turning back into Jeshir (who he himself is an old deity, but that’s a story for another day.) Obviously, Dawn was incredibly shocked that this ancient being had just turned into what looked like a unconscious human man in front of her eyes, but in this situation, her rational nature came in handy. She shoved all her questions to the back of her head and focused on getting him out of the Distortion World and to medical care. Later on, once his identity was established, she agreed to vouch for him (being Champion, she had the clout to do so). She was very eager to learn about him, and he grew interested in getting to know her as well. It was the start of a strange but beautiful relationship.
Where their first date was: It took a long time for Dawn to realize her feelings towards the old god were romantic, as is typical for her. Jeshir understood this and took things as slowly as he could, but eventually he got a bit fed up waiting for Dawn to try and figure things out on her own, so he directly asked her out. They had gone to this café many times in the past, but this was the first time he framed it in the context of a specifically romantic date. Dawn was hesitant to just go on a date out of the blue, but Jeshir’s rational was that if she thought of it as a date beforehand, then she could decide if she liked the idea of them being a romantic item: if she did like it, then it would be their official first date, if she didn’t like it, then it would just be another of their regular outings as friends. This plan seems to have worked, since by the end of their time at the café, they were walking back to Dawn’s house hand in hand and Dawn felt secure and confident in her newly realized romantic feelings.
When they had their first kiss: They had their first kiss after their first official date. After Jeshir walked Dawn home, she turned around before opening the door and gave him a quick peck on the lips, which shocked him greatly. It had been a very impulsive move for Dawn, so she used his shock to just head inside before seeing how he reacted and before he could see how flushed the action made her.
Who cooks: Dawn is the better cook, since Jeshir never learned, being a deity who doesn’t need to eat, but Dawn is also the busier one and rarely has time to cook for her family, so when Jeshir first moved in with her, he made it his mission to learn to cook so he could do something nice for his girlfriend. He’s gotten pretty good at it over the years (the way he tells it, he was always a good cook), so now he always makes sure to come home from his volunteer job at a local history museum (being an ancient being has its perks in the field of history and archaeology) to cook dinner for his wife and daughter and any guests they might have that evening (usually Ash and Paul’s family). After Tanith leaves to go on her journey, Jeshir is sad he can’t cook for her anymore, so he starts inviting the Rozanov-Ketchum’s over even more. The four them are turning into a group of middle aged parents with empty nests, haha. 
Who proposed: Dawn proposed. Jeshir always talked about Dawn spending the rest of her life at his side, but as always he let her take the relationship at her own pace, so he waited for her to decide if she wanted marriage or not. Either way, he was happy just being with her. Dawn herself didn’t really think of marriage either until after Tanith was born. She realized that seeing as they had a family now, it might make more sense if they were married as well. She wanted to at least make the proposal romantic, so after some advice from Lucas, she took her partner to one of their favorite date spots – the lighthouse overlooking the sea – and asked him to marry her. No need for rings or anything fancy, just a promise of the commitment they already knew they had. 
The dominate one: Jeshir for sure. At first especially, Dawn is less confident in her preferences and lets him take the lead as she trusts him, but later on when she is more comfortable with what she likes, she grows more bold as well, which always pleases her husband. The two end up being both quite….. bold and experimental.
Their favorite pastime together: They are definitely more of a quiet couple, so perhaps echoing the circumstances leading up to their first meeting, one of their favorite things to do together is go for a walk out to a local park or further out into nature (and even sometimes the Distortion World) and have a picnic and just relax together. Sometimes it’s just the two of them, but they often bring Tanith along as well.
Who kissed who first: Dawn kissed Jeshir.
Who is the flirt: Jeshir 100%. Dawn is horrible at flirting and much prefers direct declarations and gestures of love. That said, she’s also terrible at recognizing when someone’s flirting with her as well, so Jeshir doesn’t flirt with her much since he knows it will probably go over her head or confuse her.
Who is the romantic: Again, probably Jeshir, but Dawn has her moments as well. She usually likes to surprise him by sneaking a bit of time off work (hard to do when she’s the Champion after all) and arranging some kind of date for the two of them. Jeshir is much more domestic (not that he’d ever admit it!). He loves to cook for her and pamper her – back and foot rubs, bubble baths, cuddles all evening long…. the works. He’s a very affectionate husband and that shows in all the little romantic gestures he does for his wife.
Who wakes up first: Dawn usually wakes up first, but Jeshir always wakes up when she does since he doesn’t really need sleep so can just wake up whenever he wants without feeling grogginess. Dawn, who requires at least three cups of coffee in the morning to function, resents this trait. Jeshir likes to tease her about it sometimes if she isn’t looking too murderous (usually after her second cup.)
Who comforts who the most: Jeshir usually, just since he’s so affectionate. Dawn’s work is stressful so he tends to help her unwind. All the same, he’s not had an easy life either and sometimes the weight of things can drag him down, though he hates admitting weakness, seeing himself as above such things. Dawn is not the best at being comforting, but she always tries to at least be there for her husband whenever he seems particularly distant. She knows him well enough to tell when he’s faking cheerfulness, so she always shows him that she’s there with small gestures when she senses he’s feeling down.
The cuddler: Jeshir. To the point Dawn needs to remind him to lighten up the cuddling a bit sometimes since she’s feeling smothered.
The big spoon: Jeshir. He’s a tall and fairly broad guy and Dawn fits perfectly in his arms. He likes to hug her from behind while she’s working which, while she appreciates the gesture, often gets in the way of her actual work. Dawn minds much less when he’s cuddling her in bed though.
