Thanks for the ask! I’ll go for Willopeia, WillowsRath, and Boothbosca.
1) What, specifically, was the catalyst for their physical attraction (if applicable) to the other character? In other words, what in particular had them like “Oh, they’re…hot…”
6) How do they react to the realization that they like the other character? Is it an “oh my god I’m never going to think about this again” thing, or are they pretty comfortable with it?
12) How much independence do they prefer in a relationship—do they want to share their lives as much as possible with their partner, or do they prefer to mostly do their own thing and let their partner do their own thing?
18) They’re going through something incredibly difficult—perhaps they’re very sick, have lost a loved one, or have gone through a traumatic event. Do they ask for or accept support and care from their partner, or try to isolate themselves?
Willopeia
1) For David, it would have been after Sprout put them together for an assignment during one of KC’s catch-up lessons. For KC it would have been seeing David whacking bludgers for Quidditch practice.
6) Neither of them are complaining when they realise they like the other. KC is very comfortable with the idea of liking a tall, sporty guy with good hair. And let's face it, KC is a gorgeous girl who can kick David's arse, that's right up his alley.
12) David and KC are definitely a mix. On one hand they both deeply value their independence. On the other, they would also run the Quidditch camp together and be together as much as they can.
18) KC might try to be strong and try to distract herself somehow though she would accept David's help and support. David is more likely to actively seek KC out for support and she would gladly provide him with whatever comfort he needs.
Willowsrath
1) David has had a crush on Erika since he got to know her in second year, while it went away after she let him down gently, it came back with a vengeance after Erika kissed him at the end of his fifth year. Erika realised she was attracted to David at the beginning of her fifth year after realising he would be one of the people she would miss the most.
6) David was admittedly nervous when his crush didn’t truly go away after Erika let him down. Erika was more anxious about liking him since she didn’t want to make it seem like she was trying to mess with him.
12) These two are more independent from each other, preferring to let the other do their own thing but will always be willing to make time for each other.
18) Erika would still remain stoic but she would really be hurting and want David at her side. If it’s the other way around, David would seek Erika out and while she might not offer comforting words, she’d hold him close as an assurance that she’s here for him.
Boothbosca
1) For Amelia, she had a crush on Chiara throughout her Hogwarts years starting from her fourth year but with everything that happened, she didn’t really get the chance to act on it. Chiara realised it after being concerned with Amelia’s safety during the war when the Order learns her apothecary was destroyed.
6) Chiara was initially freaked out because while she had still made friends she wasn’t sure about being in a committed relationship, knowing that her partner would have to deal with her transformations. Admittedly, Amelia was apprehensive about Chiara’s lycanthropy but reasoned she could help brew wolfsbane potions.
12) These two definitely want to share a lot, especially since it helps the two of them relax from their stressful jobs as a healer and magizoologist respectively.
18) Both of them will actively seek out comfort from the other. Chiara was one of the first people Amelia sought comfort in after Alder’s death.
Erika Rath, bar manager at a night club in the city centre of Liverpool. She prides herself on running a tight ship, making sure her staff are nothing but the best of the best. Prides herself on professionalism, which means no workplace romance.
Enter David Willows, her second-in-command. Charismatic, handsome, knows how to handle himself in a scuffle, the perfect barman to attract club goers. Never has been one to follow the rules when he thinks they're bullshit.
Some say Erika may defy her own rules for David. She would brush those thoughts off but they may not be entirely wrong...
Do not disturb Erika unless she's had at least two coffees before 9AM, invariably this leads to coffee shortages.
Brings up adopting a pet:
David, he already had a crup called Rusty and Erika loves that magic doggo. So it was very easy to convince her to adopt another one.
Kills the bugs:
David prefers a let it out approach, Erika just squashes them.
Cooks the meals:
David is the better cook out of the two of them, leaving him to usually cook the meals.
Gets into Holidays way before they should:
Erika thought it was somewhat endearing when David started getting ready for Christmas in mid-November. She had to draw a line when he started getting Christmas stuff before Halloween.
Initiates the couple selfies:
Erika, usually with David having his arms wrapped around her. Likely playfully rolling her eyes but secretly enjoying it.
Forgets the birthdays and anniversaries:
Surprisingly it's Erika. Usually resulting in a mad dash to organise things while still maintaining her normally stoic composure.
Always ends up with too much junk food after grocery shopping:
This depends if David has kids or not. If he doesn't then no. If he does... he's coming home with a lot of junk food.
Nicknames the other:
David does, his favourite ones being Eri and Harpy.
❥: who is more likely to plan something big for valentine’s day?
David is definitely more prone to a flashier display including large flower arrangements, fireworks and a declaration of love via howler. He goes all in with telling the rest of the world how he feels about Erika.
Erika is far more subtle, an invite to somewhere more private, champagne and more than a few flirty words. Though no less shows her absolute adoration for David.
Erika watched in fascination as David wordlessly whipped his wand through the air, weaving spells together, repeating the action until all sides of the tent were covered. He gave her a knowing smirk, "Somethin' to keep out the pests, shall we?"
Of course, always ready to give the best buff Slytherpuff couple some love! 💪💚💛
3) Who compliments the other in front of everyone?
I feel like David would be most prone to this, especially bragging how it was Erika who trained him. Complimenting how her methods really honed his abilities.
10) What is a small thing that one another does to make their partner happy?
Erika loves when David gently runs his fingers through her hair.
David loves when they relax together and Erika will rest her head in his lap.
They're small gestures but just so intimate between the two of them.
13) Who likes to give the other hugs from behind followed by a kiss?
Surprisingly it's Erika. Usually she'll rest her head on his shoulders and gently kiss them and occasionally David's neck.
You should have never gave me more than one option, my friend 🤣 I’m terribly curious about these
David x Merula:
Pre-Relationship (6), General (8, 9), Love (3, 9, 11), Domestic Life (2, 7, 9)
David x Erika (I’m eager for this one)
Pre-Relationship (5, 6), General (1, 3, 5, 8), Love (1, 5, 12), Domestic Life (1, 2, 10)
Oof... @judediangelo75 you’re putting me to work here, not that I mind because I absolutely could gush about them all day.😂 Under the cut because this is gonna be LONG!
David x Merula (WillowSnyde)
Pre Relationship
6) If you had told one of them the other would be their soulmate, what would they think?
(Takes place in third year)
David: “HA! That’s a good one, me and Snyde, soulmates! You must be havin’ a laugh?” 😂
Merula: “...I’m going to give you exactly a second before I pummel you with Flipendo.”
*One year later*
David and Merula: ...Fuck
General
8) Who gets jealous easier?
David tends to put on a show for the fans, often socialising with them. Now Merula trusts David won’t cheat on her 100% but she can’t deny the attitude of certain overzealous fans irks her, especially those who try to slip him love potion. Likewise, David isn’t above a bit of jealousy either.
9) Who whispers inappropriate things in the other’s ear?
They both do it to each other in private, blushing is guaranteed at the very least.
Love
3) Who uses cheesy pick up lines?
David, Merula usually rolls her eyes playfully at them. Though a favourite of hers is “Did it hurt when you fell from heaven?”
9) Who’s more protective?
I’d say Merula being the one who openly defied her family to protect him though while David knows she can handle herself, he would absolutely destroy anyone who so much as harmed a hair on her head.
11) What are some songs that apply to their relationship, in-universe or otherwise?
... I’ll be completely honest, I’ve never actually thought of that 😅 I’m gonna have to get back to you on this one.
Domestic Life
2) What’s the wedding like? Who attends?
Oh it’s extravagant, befitting of a rising name in the Quidditch world marrying a similarly-renowned Curse-Breaker. David’s father, step-family and his mother attend. As do all of his friends from Hogwarts, Rowan is his “Best Man”.
7) Who kills the bugs in the house?
David tends to catch and release the bugs, Merula has stared down Needle and frequently came into contact with bugs on her curse-breaking ventures, finding them in the home doesn’t really phase her unless they’re causing damage.
9) Who’s more likely to convince the other to come back to sleep in the morning?
I think after everything that goes down, both suffer from nightmares occasionally, usually the other stays up with them until they come back to bed, no matter how long it takes.
David x Erika (WillowsRath)
A/N: Let’s just say this is an AU where David and Merula don’t get together.
5) Did either of them try to resist their feelings?
Erika did on account of having already let him down gently though couldn’t deny her protege was starting to look quite handsome after his fourth year...
6) If you had told one of them that the other would be their soulmate, what would they think?
(Erika’s sixth year (David’s fourth))
“Yeah right, I’ve already told David he’s a sweet lad. He’ll make someone happy but it’s not going to be me.
*One year later*
Erika: ...Fuck.
General
1) Who initiated the relationship, and how did it go?
Erika did shortly before she graduated as both were going into Quidditch they knew it would be complicated to get together so they held off on it publicly but wanted to keep a relationship up in secret.
3) What was their first kiss like?
In same meeting as Erika initiating the relationship. It was just the two of them in the changing room, away from prying eyes. They had a bit of a heart-to-heart about the future and Erika just went for it. Though honestly shocked, David leaned into the kiss.
5) What’s their height difference? Age difference?
David is 5′11′’ by his sixth year and Erika is 5′10′’, so just an inch. Erika is two years older than David.
8) Who gets jealous easier?
Erika occasionally but she tends not to let it show, David however will snake an arm around her waist if he knows she’s getting jealous.
Love
1) Who said “I love you.” first?
They both did in private but after retiring from Quidditch at the same time (David was 28, Erika was 30), it was Erika who proudly declared she was in love with David Willows.
5) Who initiates kisses?
David is more likely to do it in public, Erika prefers kissing him in private.
12) What kind of nicknames do they call each other?
David just calls her “Rath” mostly because it sounds cool, she in turn will just call him “Willows.”
Domestic Life
1) If they get married, who proposes?
David is the one who proposes to Erika after they make their relationship public. Without any potential scandal from two quidditch players on rival teams being together (David on the Wasps, Erika on the Harpies), they’ve had enough of skiving around and dodging The Daily Prophet so they go the whole nine yards in announcing their relationship.
2) What’s the wedding like? Who attends?
In contrast to their status as sport stars, they had a very simple ceremony, only inviting close friends and family.
10) Who’s the better cook?
David is by a long shot, though that’s not to say Erika hasn’t tried and usually the result has been good.
I'd say David, he knows Erika can handle herself but if she asks him to he'll gladly throw hands for her. While Erika would definitely be more stoic about it, she's no less fierce when she gets protective of him.
One thing they can both agree on protecting the other from: Daily Prophet reporters.
