SEND A "SHIP ME" AND I'LL ANSWER THIS ABOUT OUR MUSES.
The most possible scenario would be starvation, considering their lack of cooking skills, but in the critical moment, I guess they’d use some of their intellect to prepare something edible. They both don’t mind experimenting so who knows? Perhaps they’d manage not to burn the kitchen down and make some decent meal?
how often do they fight?:
Not very often. I could imagine them both being likely to compromise, instead of fighting. Seulgi is a free soul, yet it goes well with Wendy’s natural pursuit for knowledge and discovery. If their opinions differ, they would be likely to listen to each other and try to understand each other’s point of view.
what do they do when they’re away from each other?:
Since her childhood, Seulgi has been embracing solitude and doing quite well on her own, just as Wendy, who tended to discover and learn quickly, always spending her time on reading and observing. If they are separated, each of them would use it as a peaceful moment. Seulgi would probably do some yoga and Wendy would snatch another book to read.
nicknames for each other?:
Surely something concerning their elements, yet I don’t think they’d even bother to use some special nicknames. Too illogical.
who is more likely to pay for dinner?:
Probably because of Seulgi’s stubborness in saying no to that, for the sake of peace, Wendy would pay.
who steals the covers at night?:
Definitely Seulgi. Despite her naturally cool skin, lower temperature of her body, she gets cool very easily, even putting on an extra t-shirt or sweater during winter. It would be some sort of instinctive action. Perhaps, they’d fight for the covers at times, eventually cuddle. Of course, just for the sake of the warmth because it’s logical.
what would they get each other for gifts?:
Books from Wendy’s part and pieces of clothing from Seulgi’s. Everything that would stress their personalities and individualism. Seulgi is quite sentimental, so perhaps, she would try to get Wendy something meaningful and quite valuable, while Wendy would surely think of useful gifts.
Seulgi with her eidetic memory would remember the littlest details, mostly images, but also the most random things. Wendy would pay attention to the most remarkable and essential matters.
Seulgi. When upset, she’d lose control over the words slipping past her lips.
what would they do if the other one was hurt?:
It would be a particularly complicated situation, considering their little ability to express emotions. If Seulgi was the one to hurt Wendy, it’d take her a while to apologize or express her apology in a human way. After hours of grumbling and huffing, she’d feel bad for hurting Wendy, yet she’d be the one to soothe the situation with words mostly, as she’s not very affectionate. Wendy, on the other hand, despite her usual silence, having a better bond with emotions, even if they are still hidden, she’d be likely to approach Seulgi and eventually after hundreds of “I really don’t understand you.”, she’d initiate some contact, perhaps. The action itself, as it comes from someone Seulgi is close with, would be a good step in their possible reconciliation. Depending on how serious the situation would be, Seulgi may get much more caring and altruistic, even admitting that it was her fault.
It would be a very awkward moment as they are both clueless and rather shy in terms of affection and physical contact.Despite their lack of experience in this field, I think Seulgi would kiss first. It is probably the fact she’s naturally confident and curious about everything, including such matters.
who made the first move?:
Even if the kiss was initiated by Seulgi, Wendy would make the first move. Why? Because Seulgi is a very oblivious one, unless she’s told clearly about the matter. That’s why she’d need an impulse and someone to initiate the first move. And here comes Wendy… oh.
who started the relationship?:
Hard to tell. They’d be likely to talk about it and perhaps come to decision of relationship.
