Can I request Yin and Jin crushing super hard on Shy!Younger sister of Mk, they're both trying constantly to get her attention and win her over, and the gang is not happy about it (especially Mk)
Assistant Demon: What are doing, you oafs?
Yin and Jin: She's pretty~
Assistant Demon: And you're ugly now get back to work
Lol thank you for this, also it turned out way longer than I thought it would
Yin & Jin x MK's Shy Younger Sister Reader Headcanons!

stupid lovesick fools --is how the assistant demon describes these two when she first finds out about their crushes on you. she is the backbone of their group and she does not understand why they can't JUST FOCUS ON TRYING TO WREAK SOME CHAOS
I imagine they came across you on accident. you were just there with Mei and MK, probably getting some food and TRYING to have a chill day with your bro, but then they came along like "HAHA FIGHT US MONKIE KID--oh hello who's this??" and they instantly tried to poke their noses into your business.
obviously MK whooped their asses for even going near you(he is very protective of you dammit)
Mei is also upset(bc if MK gets upset so does she) and she will whoop their asses too
The assistant demon shows up to collect the boys and instead of the two of them being upset they lost as usual they're instead........rambling and gushing about this cute girl they saw??? she doesn't understand.
Yin and Jin become a real thorn in MK's side for the next few WEEKS because they've learned where he is, you aren't far behind
you're freaking out bc why are these demons so interested in you?? but they're like being super obvious about their crushes--they ABSOLUTELY sat outside your house with a boombox and some flowers and "whatever else human girls are into these days"
Pigsy and MK scared them off because it was 3 in the morning
eventually the two of them caught you alone, and very quickly tried to explain why they were there--trying to make it brief just in case MK might be lurking somewhere
they're very sweet about it, they politely ask you out, and you do your best to explain to MK and Pigsy and Tang that you've simply caught the boys' fancy and you're gonna go on a date with them to give them a chance!!
everything goes smoothly(about as smoothly as it can with those two), but expect to see three poorly-disguised men following along at a distance. it's just MK, Mei, and Pigsy in trenchcoats, sunglasses, hats, and fake moustaches--don't be alarmed
.....yeah, it's gonna be a little awkward having Yin and Jin over for dinner
