so! mallory's lohen being the most jealous of the lohens is a really funny mental image, huh? at least for everyone who's not mallory.
ESPECIALLY after he finds out she's worried about the depth of their relationship. some might say that the intensity of the affection he's showing her is a red flag, but... it never really goes away or fades. nope! every day he's acting like they've only just gotten together, kissing her and holding her and speaking so lovingly like it's the first time he's done any of it. to say nothing of his excitement in the bedroom... but that's not the focus at the moment!
shall we imagine, for a moment? he knows mallory loves to tease him, and he finds it adorable, after all. it's just part of her personality, right? but the idea of her getting too... comfortable and teasing someone a little too much that isn't him, let's say, drives him crazy. it's not uncommon for him to send one of the knights to trail her from a distance with the excuse that it's a route commonly used by travelers. none of the knights are fooled, especially since he always only sends one at a time, and he rotates the knight in question each time. he'll do the route himself if he's feeling especially concerned about whatever and/or has the time away from work. mallory can be her usual self. he doesn't want her to change, and it is something he has to grapple with a bit. but it does bug him to think that someone else might be getting that same loveable bratty act...
lohen is dedicated to protecting people, and so while he definitely has urges to just... deal with anyone that dares to flirt with mallory anyway, he holds himself back. if they do something untoward like stealing from the markets or harassing someone, or try to bother her beyond her comfort, though... well, it's okay if he goes a little overboard punishing them, right? after all, they ought to know not to touch what belongs to other people!
i can see them having the "you're the most jealous man i know!" "you know other men?" convo. lohen tries so hard to make it as a joke, but it's clear from the slight second between him saying it and grinning at her that he can't quite shake the feeling. there's a good reason he marks her up every time they sleep together! he's just... making sure no one else looks for too long! that's all!
now shall we discuss the bedroom then? his love is intense, it always is, but it's especially so on nights that he's feeling especially jealous. making her cry out his name louder and louder, marking her everywhere modesty be damned, giving her so much pleasure her mind goes totally blank save for knowing it's him that's giving her that pleasure... and, well, with plenty of other reminders of his love! including some dripping out of her, if she'll let him. and, uh... oh, damn, are those dents on his headboard that bad now?
of course, he won't let her go without making her return the favor. he's far too happy to have her bite and scratch him up, moaning and begging her to do more. to hurt him with it, to let him know she adores him as much as he adores her. perhaps a tall ask, but well... mallory's equal to the challenge, yes?
Now El, your mistake is that you think it's a problem for her. It's everyone else's problem.
Mallory is shockingly unaware, or maybe just unbothered? It's hard to tell. Oh Mallory, what sort of maladjusted, lonely life do you lead that you find Lohen's more concerning behaviors endearing, charming, or even hot?
See, her teasing others the way she does Lohen is not as big of a concern as you might think. She acts up with him so much because she has feelings for him, and that's how it comes out for some reason. To be fair, I see him being much the same way. In my mind, when Lohen has someone he likes, he has someone he likes to mess with. Like cuteness aggression, in a sense.
When it comes to men, Mallory's not especially eager to talk or get close to most of them in the first place. Especially the drunkards that Mondstadt is no doubt filled with. How she fawns over women is another story entirely but that's neither here nor there. If anything, having a menace of a boyfriend who's more than eager to scare them off is good! Encouraged, even. Either way, they're never going to get the same treatment Lohen does. If she's ever acting too friendly, just know it's deliberate. Either to prove a point, or to be petty. It's a provocation. Part of her really delights in how bothered he gets over her, since his usual demeanor is so unshakable and confident. Makes her feel special, makes her feel wanted. (Seriously. Mallory, who hurt you?) Plus that's just more to tease him for! He teases and bullies her so much, she needs whatever she can get to try to get even!
"Awww, is someone jealooouus...? Do you want me all to yourself~??? Who knew the vice captain was such a passionate man~? Hehehehee!" She's just eternally striving for the day she can make him the one who's flustered. Who knows if she'll ever get it.
Oh how I wish I could see the faces of the other fifth company knights seeing their notorious vice captain being so affectionate. Could they even fathom him showing such fondness for something that wasn't bladed? But to her, in a way that must seem twisted and backwards in their eyes, Lohen represents safety. If the sharpest arrowhead of the fifth company pointed itself at whatever threatens you, you'd feel damn safe too. As unorthodox of a knight as he may be, (and frankly, that's what Mallory likes anyway...) he's a protector. She'll tease him about any knights sent after her too. You think she won't? "You fretting over little ol' me? You worried I'll crumble to dust if you don't keep an eye on me? I must be reeeaaally precious to you, huh?" More snickering.
But honestly, most times she'd probably wait to venture out until he can accompany her anyway. It's not like she's a knight or an adventurer, she's just a feeble artist. No reason to put her delicate self in harm's way. I mean... unless he wanted her to be a damsel in distress? Throw herself into peril (within reason... the kind of low level enemies he could easily clear out at a moment's notice if he really needed to or thought it was going too far. So yeah, within reason. ...if you can call any of this reason.) so that he can save her, armor (and blood of his enemies) glistening as he tears through any threat that may stand between them, before reaching her and...? Ahem. Anyway. Combining his love of battle with another activity he very much enjoys? If he thought he might be into that, she'd consider trying it. For him, out of her own boundless generosity, of course. That concept definitely doesn't do anything for her. No sir. That would be crazy, right?
Another misconception, my dear el! He doesn't have to "make" her return the favor at all! Doesn't even need to ask! She insists upon it, as if she thinks she's getting even with him for the embarrassing marks he's left on her. (Ohh noooo... don't mark him back.... that would suucckkkk....) She looks so smug about her "revenge" too... should we tell her?
(Also, beneath the suffocating embarrassment of it all... she does get a sort of thrill and pleasure out of being marked like that. Like she's being claimed, in a way. But we can't acknowledge such humiliating things! Hush!)
"If she'll let him." Dear sweet El, my sweet summer child, the things her Lohen could tell you... I mean of course he won't, a gentlemanly knight such as himself could never, so he won't! He definitely won't tell you about how she absolutely begs for it once she's too fucked dumb to brat or pout or think anymore. If flustering her and calling her bluff shuts her up, this state is more like the floodgates opening completely. No more filter, no more shame. Just pure, honest adoration, praise and submission. Oh such sweet submission. She'll be mortified by it later, of course. In that regard she too is acting like it's still their first time, every time... but you would too if you said some of the humiliating shit she did in the heat of the moment, okay? Good thing such a benevolent man as Lohen would never hold that over her head like the fucking Sword of Damocles. No, no no no! Not at all! ^^
So all in all, she's having a great time! No notes!
