How they first met: They first met in Accumula after Ghetsis’ rally! N was interested in interacting with Hilda as a trainer to ‘convert’ and Hilda thought N was a weird protester and just sort of indulged him since she tries to be respectful of all ideologies. 
Where their first date was: Their first actual date was when the twins were about three years old. It was all very proper and set up in advance, since the two wanted to try out going on a date to see what it was like and if it felt right for them. They went out to a dinner and movie in Nimbasa, pretty ‘stereotypical’ date material. 
When they had their first kiss: Well, technically, their first kiss was when they hooked up at Bianca’s Halloween party, but their first kiss while dating was right on the first date. N kissed Hilda during the credits of the movie, then immediately apologized for being forward, though Hilda didn’t mind and said she would be fine with going further once they got home or not, depending on what he wanted. 
Who cooks: Hilda is the better cook, but N is usually the one home to do the cooking since their home is right above the pokémon shelter he mainly runs. His cooking is pretty good, but he tends to stick to the recipe by the letter, rather than getting more creative like Hilda does. Once the kids are older, however, Euphie usually cooks, since he’s quite the skilled chef.
Who proposed: Hilda proposed! Her mom and the twins helped her set the whole thing up, from choosing a ring to finding the perfect location. At this point, she knew N would say yes, so it was all about the celebration. After he accepted her proposal, the twins burst out of hiding and, though they were meant to give bouquets to the happy couple, ended up throwing the flowers on them instead. It was all pretty hilarious. They had a small party in Nuvema at Hilda’s childhood home afterwards.
The dominate one: Hilda is more consistently dominant, but N can easily be more dominant than her when he wants to be, though he tends to be more flexible.
Their favorite pastime together: Working at the pokémon shelter together is a favorite. Hilda is so busy with her Elite Four job that just unwinding by taking care of pokémon with her husband is something she looks forward to. As for more romantic pastimes, while they don’t live there, if they have the time, they like to go to Nimbasa to visit the amusement park – especially the ferris wheel, of course.
Who kissed who first: N! Both during their one-night-stand and when they started dating.
Who is the flirt: Neither, actually. They are not a super flirty couple and prefer to show their affection through smaller, non-verbal displays.
Who is the romantic: N, usually. Hilda can be a bit stiff and formal at times, especially when she’s tired after work, so N likes to help her unwind by pampering her and showering her with romantic gestures. He gets really into the idea of romance and the like so getting her flowers and setting up cute dates is a hobby for him.
Who wakes up first: They tend to wake up at the same time, typically. Hilda is perhaps a bit more of an early riser, but a good amount of the time, N will wake up before her. It really depends on the day. Both of them kind of like to watch the other sleep though, if they wake up first. It’s comforting seeing their spouse so at ease.
Who comforts who the most: Hilda usually comforts N more, simply because N has had the more upsetting life. She’s gotten tuned in to the things that can cause him to panic or react negatively as a result of Ghetsis and Team Plasma and how to help him in those situations. That being said, N also knows that Hilda tends to internalize her own problems and hates when she takes care of him but not herself. As a result, he’s also gotten good on picking up when Hilda is bothered by something, and knows just what to do to help her feel better or just provide a shoulder to lean on.
The cuddler: N tends to be more physically affectionate, often curling up to Hilda like a cat, but his wife has her moments as well. The two aren’t super big on PDA though, nor physical affection in general, so most of their cuddling is when they’re at home alone and sitting together or in bed.
The big spoon: They switch! N is taller, so he often will be the big spoon, but then Hilda will complain he’s too bony and his elbow is poking into her so she’ll demand to be the big spoon instead. Either way, even if they start off spooning it doesn’t last long, since it’s not really either of their preferred cuddling position.
