Based on this request on my tumblr blog:

may I ask for something where they react to MC falling in love with someone else (not the main 4)

.•°¤*(¯'★'¯)*¤° °¤*(¯'★'¯)*¤°•.

You have fallen in love with a young man that sells flowers and bouquets at a stall in front of the Hunter Association HQ. Every day, you'd got flowers from him, and somehow you started talking and after a few weeks even dating each other. He confessed to you recently, and you accepted his question to be with him, not wanting to wait any longer for any of the other men in your life...

Zayne

- Zayne asks you during an examination why you haven't spent any lunch break with him in the last weeks and if something is wrong between the both of you

- And so you start to tell him of your new boyfriend In that second he completely freezes for a second, the stethoscope halting in midair as he was to put it back in its place at his coat

- His eyes marginally grow wide before every emotion subsides and a complete neutral gaze meets yours "Does he care for you?" is his only question, stated in his calm and soothing voice, and you nod with a bright smile, completely unaware of his reaction to your revelation 

- As you leave Zayne's office to meet your beloved outside, he watches you walking away from his doorstep, not aware of the devastation and longing in his eyes

- Soon after Zayne throws himself in even more work, spending every free second in surgeries or important research

- He even takes a months-long trip to Mt Eternal, helping Dr. Noah, trying to forget about you, even if you are the reason he does what he does. He still is your primary care physician even if most appointments were done by Dr. Greyson now

- You only get to see Zayne twice a year, his eyes devoid of emotion when looking at you and his demeanor even colder towards you. He's being the complete professional doctor he should be from the beginning...

Rafayel

- Rafayel finds it out you are together with another as he surprisingly wanted to pick you up after your last mission

- Seeing you holding hands with that guy from the flower stall, he nearly wants to throw up on the spot

- In unspeakable cruel pain he touches the hidden mark on his chest, but retracts his hand nearly immediately as he slowly strolls up to you and the other man

- An awkward tension is built as you introduce the two men with each other

- Rafayels  cold gaze checking out the other guy, but to your concern he says nothing 

- A sweet smile that doesn't reach his eyes is sent to you and asking how long you two are together. You feel a bit interrogated as Rafayel asks some more about your relationship with your love, but you answer him honestly nonetheless.

- And after all "Well, I don't need a bodyguard anymore. That's why I came here today, miss. Thank you for your extraordinary services" a little grin at his ambiguous choice of words towards the other man "I wish you all the best." before he turns around, leaving you completely stunned.

- Back in his atelier he breaks down, letting his anger and disappointment roam free in form of his flames devouring every art piece that reminds him of you

- Hours later he walks into the ocean, resolved to never return again. Why did he wait so long for you, making every effort to protect and court you? And there you are, throwing yourself into the arms of that other man. 

- As you want to visit him at his atelier for explanation why he fired you so suddenly, all you find is a burnt ruin and a handful of pearls laying between the ashes.

- As you look to the ocean, the waves are adorned with some beautiful sea foam that shimmers purple and blue in the faint sunlight...

Xavier

- Xavier meets the two of you in front of your apartment as you kissing another man

- Suddenly all the lights in the building go off, and pitch black darkness surrounds you. You scream out in surprise, not knowing that it was Xavier's evol causing the black-out 

- Just seconds later the lights are back on and you see the silver haired hunter in the hallway, staring at you with dark and cold eyes

- But he isn't glaring at you, no he locks a deadly hunter gaze with the man you kissed just before 

- Xavier is striding towards the two of you with the movements of a predator hunting his prey "Won't you introduce us?" he is asking you, deadly calm and not even spare a glance at you

- As you explain your relationship to your neighbor, your boyfriend says he's better going, seemingly sensing the danger that Xavier is emanating 

- With a faked polite smile, Xavier demands to escort him out of the building, not giving you a chance to intervene, he just want to talk more with your boyfriend 

- As you start your work the next day, Xavier has vanished, and you've been told that he took all his collected vacation at once and won't be at your side for months

- Sometimes you'll get reports that some tenebrae are killed in the N109 Zone, but that is all that relates to Xavier

- Some weeks later these reports stop and Xavier is back, doing missions with you as nothing has happened. Surprisingly your boyfriend broke up per text message two weeks ago and even his flower selling stall is missing. As if he never existed despite the short message on your phone...

Sylus

- Sylus learns from your relationship via Mephisto

- As the bird reports him, that you've been seen kissing another man during a "business meeting" he looses his composure and his "partners" are gone 

- He sends a bunch of text messages asking if you had fun and if you're now to busy to visit him

- You're concerned, knowing that there was more between you and the leader of Onychinus but both of you never admitted that openly

- Texting him that you're in a relationship and that he has to stop observing you 

- Sylus never answered to your last message

- The weeks and months after this he's just sitting in his base, watching the reports Mephisto made from his observings

- everyone in the N109 zone doesn't dare to approach him, because they never saw their boss this cold and heartless before

- luke and Kieran the only one still able to talk to him, but with utmost care because his temper is uncontrollable, and his patience really is nonexistent now

- The complete territory is in fear of his ruler

- like a crow in his nest he sits, waiting for you to return to him, because what does this man have that could satisfy his kitten long term

- you are his, you just don't know .... Yet.
