How they first met: Zinnia was actually the first person to find Sukarno after he turned into his human form. She was studying the murals in the Sky Pillar and making sketches of them for a plan to restore the artwork. All of a sudden, she felt the air shift and heard a loud roar, followed by a crash at the top of the tower. Zinnia ran up the stairs as fast as she could, only to find Rayquaza themselves lying in front of the altar. In fear of what possibly could have injured the great deity, Zinnia ran up to the dragon only to find them transform before her eyes into what looked like a member of her own clan. Bewildered, Zinnia had to let logic take the backseat as she moved to place her cloak around the man as he slowly gained consciousness, clearly disoriented. When she found out he didn’t speak League Standard and seemed to think it was centuries ago, she began to get worried again about what possibly could be going on. All the same, she managed to convince him to come with her to a hospital and after they figured out he was, essentially, a time-traveler with superpowers (seeing as all his memories of being a deity were missing) Zinnia was the first one to offer Sukarno a place staying with her (and his) clan in Meteor Falls.
Where their first date was: Originally, the two spent a lot of time together as Zinnia took it upon herself to introduce Sukarno to the modern world and everything that had happened since he was last mortal. As such, they traveled across Hoenn together, also hoping to maybe find other former-deities like Sukarno or gain clues as to why this happened in the first place. After their journey ended, however, Sukarno found himself making excuses to ask Zinnia questions about modern lie he already knew the answers to, just to spend time with her, while Zinnia would go out of her way to discuss history and Kaliya clan lore with Sukarno, even if she could find the answers elsewhere. Since neither seemed to be catching on to the other’s feelings, Zinnia’s grandmother just set them up on a date at a restaurant in Fallarbor Town. Needless to say, it went well, as much to the clan elder’s delight, Zinna brought Sukarno back to her home in Meteor Village that night.
When they had their first kiss: They had their first kiss on their first date, well, after it at least. Swimming with happiness that Sukarno returned her feelings, Zinnia was excited to move to the next step in their relationship, so she invited him to come home with her instead of returning to his room in the elder’s lodge. When he agreed and they returned to Zinnia’s house, she decided to set the mood by kissing him. Sukarno did not react super well to that, since he grew up in an era where courtship was supposed to be formal and physical affections reserved mainly for after marriage. Zinnia, on her part, felt super bad for rushing him, so they agreed to just hang out for the night instead. They did eventually have a proper kiss about a month later, though.
Who cooks: When they first started dating, neither of them were very good cooks, Zinnia mainly knowing the basics and Sukarno knowing none at all. Zinnia’s grandmother tried to give her more detailed lessons since someone in the family needed to know how to cook, but Zinnia just didn’t catch on too well. Sukarno, on the other hand, got his own set of cooking lessons from his future grandmother in law and found out that, not only did he enjoy cooking, he was quite good at it. Nowadays, he’s the one who cooks for the family, since Alya inherited her mother’s cooking skills.
Who proposed: Sukarno proposed! Zinnia saw it coming from a mile away though. She knew that her boyfriend wanted to at least try to keep their relationship somewhat traditional (even though he was breaking away from the traditions he was raised with in many other instances), so she let him go through the whole process of asking her grandmother for permission (she drew the line at dowry negotiations though), then formally present her with the engraved gold charm symbolizing their union. The whole Meteor Village had a huge party for the happy couple (dwarfed only by the actual wedding) and while Zinnia was overjoyed at her future, she dearly wished her sister Aster could have been there to celebrate as well.
The dominate one: Zinnia. Sukarno makes a good show of trying be the dominant one but it’s Zinnia. She regularly tops. And her husband does like it, even if he complains, because that’s just how he is. All the same, he accepts it just fine since his wife is the ‘higher ranked’ one in their relationship so traditionally she would be the dominant one. 
Their favorite pastime together: They love to travel! Especially to foreign nations. Zinnia knows she’ll eventually be tied down in Hoenn when she inherits the clan head duties from her grandmother, so she wants to see the world while she has the chance. Sukarno never traveled in the past, so he loves being able to see the world and all the different cultures, people, and pokemon that make it up. They usually forgo public transportation and fly on their dragons (Zinnia’s Salamence and Sukarno’s Flygon), making sure to hit all the important cultural and historical sights along the way. Alya was born while her parents were travelling (which caused a bit of a scandal back home for the heir to not be born in Hoenn), and her parents like to think she inherited her wanderlust from being born ‘on the road’ so to speak.
Who kissed who first: Zinnia kissed Sukarno.
Who is the flirt: Sukarno, surprisingly enough. He might be a bit on the traditional side, but once he discovers that flirting in public is socially acceptable he takes it upon himself to shower his wife in compliments all the time. Zinnia isn’t really phased by this though, and she’ll flirt right back (which will actually fluster her husband, which she finds hilarious). 
Who is the romantic: Sukarno, again, since he takes a very traditional approach to romance, doing things like buying jewelry and flowers for his wife (she appreciates the latter a bit more than the former) and generally pampering her whenever he can. He can sometimes go a bit overboard though, in which case Zinnia will tell him to take a break worrying about taking care of her and let her take care of him. This, as expected, flusters him quite a bit. 
Who wakes up first: Sukarno, usually, since he just doesn’t need as much sleep as a normal person would. He usually tries to go back to sleep so he can wake up with Zinnia though.
Who comforts who the most: They both comfort each other quite a lot. Zinnia is still haunted by her sister’s death and the responsibility that suddenly fell on her shoulders in the aftermath, while Sukarno has lived through a civil war, seen family members and friends killed, and essentially thought he was going to die when he ended up deified. Not to mention being displaced in time on top of it all. Sukarno tends to internalize all his issues, just as Zinnia tends to be in denial about things, so often times their communication isn’t very good. All the same, if one does pick up on the other’s distress (and they’ve gotten good at it over the years) they have a wordless agreement to led support when needed.
The cuddler: Zinnia tends to be more physically affectionate, mainly since physical affection is more common in the era she grew up in. Sukarno craves physical affection more, but is more hesitant about initiating since that sort of thing wasn’t done in public, or even in private as much, where and when he grew up.
The big spoon: As he is the taller one, Sukarno often is the big spoon, but he likes being held by Zinnia as well.
