be it a medieval setting or like. HEAR ME OUT!!! Mainstream mark or one of his variant selves (im seeing viltrumite) get forced to deal with alien-princess!reader for a mission to generate goodwill or a part of the plan to take control of her planet

The best way to do that is by getting close to the reader regardless and I can see two different versions of her in this scenario. (im ignoring other lore rn)

There’s the genuinely kind and sweet reader with no concept of boundaries who is too nice for her own good and all I can see is whichever of the variants (again mainly viltrumite Mark in mind) having to save reader’s dumbass as they’re basically pretending to be the equivalent of a knight for her and poor reader is in TEARS and clings to Mark just overall super physically clingy and affectionate. id like to think this is probably the first time some of the Marks have had any kind of gentle and loving touch and interpret it in their own way and either become pathetic little puppies who just want YOUR love and affection or decide you’re now basically a chew toy for them to do whatever they want with and making you cry gives them the hardest boner ever. you stay with Mark no matter what and I’d also like to think this some of the most attention you’ve ever received in your life despite being a princess and you cling to it, even if it is Mark just bullying you.

Mainstream mark would get a different scenario but the above could work too as I know damn well Mark would fold for the sweet and nice reader but

I also see mainstream Mark as someone who gets pathetic for strong/dominant/mean women, so his alien-Princess!reader would be exactly that. he has to go to her planet to help with something or for a peace thing whatever but reader is is put under his care and vice versa. she hates it! she hates every second of it!! takes out her frustration on Mark and at first Mark is really put off and they do NOT get along at all but Mark is also in awe over how pretty she is and how she’s so stubborn and headstrong and!! Maybe you’re kinder to your people than you are to anyone of the same rank as you!! He sees that and loves it!! and maybe he watches you save yourself instead of him saving you and as you stand there in the aftermath of whatever fight just transpired, looking wrecked while standing above the bodies of those who tried to fuck with you, Mark has literally never felt more attracted to anyone ever it physically HURTS. you’re glaring at him and bitch him out for being late and how you had to save yourself and you slowly lose steam bc he’s just. staring at you. absolutely smitten. and it’s making you nervous???? bc wtf shouldn’t he be snapping back at you?? but he’s just nodding along, agreeing with whatever you say with the softest look in his eyes it’s actually pathetic and adorable. he stops being so antagonistic back to you after this and you slowly realize how much you love him and something something rest is history !!!!
